Simple, fast and effective

Quite informative. Thanks.

Dude, please! Remove the openstreetmap and switch back to Google Maps. That openstreetmap is really disgusting and annoying.

I love it it is so fun!!!

Very good service I like it

it's not distance rather displacement(shortest distance) , no matter if any river coming the way.

I wis it had morer options like walking driving and buses

I’m not a pilot nor do I fly. Airlines do not fly by this planner either. It gives you general directions from point A to Point B. That’s about it folks.

It is a very useful to manage the travel plan

The website is very useful to have an idea of distances between cities. Wish if it gives the road distances!

This is a very helpful website to use! Thanks so much!

amazing tool

Thank you for this map. Wish I could print it

I really love this distance from to and it'll make my departure easy to my destination.

With no delays can travel 50 - 60 miles in 1hhour also depends on traffic delays

Car Road distances please.

Please include miles by boat...

this is an amazing site 10/10!

Awesome tool!

How Driving Distance Is Calculated Between Two Locations

Algorithm for calculating driving distances between cities.

This route calculation tool harnesses the power of shortest path search algorithms within a weighted road graph, employing sophisticated algorithms like Dijkstra, A-Star, and Contraction Hierarchies . Unlike conventional calculators that use distance or travel time as the graph weight, our system optimizes drive time for vehicles, favoring routes on higher-class roads for a smoother journey.

The backbone of this tool is built on OpenStreetMap data, ensuring our road graphs are accurate and up-to-date. We calculate distances between road segments with the haversine formula , using precise GPS coordinates to measure the Great Circle Distance. This formula is pivotal for calculating "air distance" or "straight line distance" between two points, taking into account the curvature of the Earth.

Road distances, however, diverge from straight line distances due to the natural curvature and layout of roads . To address this, roads are represented as segmented lines, and the haversine formula is applied to each segment, allowing for precise calculation of the journey length between any two points.

Recognizing that cities encompass large areas, our tool selects a central point within each city for distance calculations between cities. For personalized route planning, users can specify exact addresses or select points on the map. Additionally, the route's start and end points can be adjusted directly on the map for enhanced customization.

Travel time calculations break down the route into segments, evaluating the maximum permitted speed for each segment to estimate the fastest possible travel time.

It’s important to note that while our route calculation relies on advanced computer modeling for accuracy, no model is perfect. We encourage users to plan with a margin for adjustment to ensure a reliable and efficient journey.

Alternative Methods for Distance Calculation Between Two Addresses

One simple way to measure distance is by using a highway atlas. By tracing a route with your eye and rolling a curvimeter along it, you can gauge the distance. Estimating travel time involves assuming an average speed of 50 miles/hour on major intercity roads. Although this method provides rough estimates, it's straightforward.

In the absence of a curvimeter, a ruler can serve as a substitute. Start by aligning the ruler's zero mark with your route's beginning and follow the road's bends closely. Then, translate the measured length into kilometers or miles using the map's scale, which is typically provided in the atlas.

For those seeking a more streamlined approach, pre-calculated distance tables specifically for the USA are available on websites, atlases, and guidebooks. Particularly useful for journeys between major cities, these tables streamline planning, although they may omit smaller locales.

An important feature of this distance calculator tool is that it is "as the crow flies", so traveling in real life will normally involve larger distances, but this may also help those who need to measure off-road distances.

Want to save your route? Try the Advanced Google Maps Distance Calculator

• Zoom and drag the map to find the location of marker 1
• Click to place marker 1.
• Zoom and drag the map to find the location of marker 2.
• Click to place marker 2.
• The distance will be calculated then displayed below the map in miles or kilometers. You can change between miles or km at any time
• Add as many points as required and the distance will build up.
• You can also drag and drop markers after they have been put on the map
• To share your route and distance calculation use the option [Generate Link For This Route]. You can then copy the link generated and send this via Twitter or Facebook.

All distances are estimations so Daft Logic does not accept any responsibility that may arise when the value reported is incorrect.

You can move the markers after they have been positioned so you can modify you route on the fly and see how the distance will be affected.

• Click [Clear Last] to undo the last marker placed
• Click [Zoom To Fit] to zoom the map around all markers
• Click [Clear Map] to erase all markers and start again
• Use the Quick Find text box to quickly relocate the map
• You can choose between miles and kilometers (km) for the Total Distance readout
• Click [Show Elevation] to get a chart showing the elevation of your route

How it Works

Clearly you, the user inputs two 'points' that are used to calculate the distance. Calculating the "As the Crow Flies" distance is a matter of using Great Circle formula . Then the main problem is converting the Google Map unit to miles and kilometers.

The map will also automatically save your route in your temporary internet cookies so that you can return and see the route as you last left it. If you ever need to start from scratch then use the [Clear Map] button.

Benchmark Tests

Map showing the Mary Peters Track in South Belfast. The reading shows 0.394km which is clearly a reasonable measurement for an athletics track.

Map showing the estimated distance between New York and Paris. All references that can be found suggest that this is an accurate measurement.

Map showing the Seven Mile Straight in County Antrim, Northern Ireland. This shows a reading of 6.910 miles.

Map showing the distance between Belfast and Dublin. As far as I can see this is an accurate estimate (if there is such a thing). This trip would be approximately 100 miles by road so the proverbial crow would have less distance to travel.

Is there any way to import a route from this Distance Calculator to the newer Advanced Google Maps Distance Calculator? By J Huang on 26th July 2024

I noticed the same thing as below and some of the Russian roads have propaganda inserted where the street name would go. On 17th June 2024

Just curious. I've been using Daft Logic weekly, if not more often, for several years. Yesterday, it suddenly overlay roads from elsewhere in the world, probably somewhere in Russia, based on the road names (POCCNR, e.g.). This morning, it further overlaid road names that appear to be British (Rudgate, York). These were visible, criss-crossing the local roads in the Johnson Creek, Wisconsin, vicinity when one zoomed in part-way. Very strange. ??? On 16th June 2024

Very nice, great tool for multiple tasks. Thanks. By Abbas Baloch on 1st May 2024

I thing is great to know how many time we need to get the place we work By Kleber Caraguay on 4th April 2024

Every time I try to do the distance calculator and switch from OSM to satellite all i get is a message in the center that says loading and it doesn't make any difference what browser I use, got any ideas whats wrong? By Tommy on 1st June 2023

This is awesome!! Maybe add an option to change the color of the markers? On 20th October 2022

Nice job! Yes, it is now working for loops, but it has a strange way to calculate distances. As I see in the map, it is as if it calculates distances in straight patterns, like flying between points. No road trips? :) At least is it using Haversine calculus or Geodesic ones for these distances? By Emiliano Llano Díaz on 26th April 2022

Saved route coordinates IS now fixed and working - including my bookmarked routes. Thank you very much! By MC on 4th June 2021

Is there a way of drawing a circle on a map with the centre at, say, my home? Because of Covid, we are limited to travelling max 5km from home. I would like to be able to create, then printout a map with a 5km radius from my house, so that I can work out legal bicycle rides to try to keep fit. By Ian Michael Baker on 28th May 2021

MC, thanks for reporting these two issues. They should now be fixed. By Daft Logic on 26th May 2021

Since map-change update - Uploading Route co-ordinates does not appear to be working. Also I have some bookmarks of routes, with coordinates saved, if I follow the bookmark, I am simply presented with the whole world map, it does not zoom to the pinned route. I also tried re-creating (part of) a route, with about 5 or 6 pins, then generating a link... it did generate a "tinyurl" link, but that link, when followed, also does not revert to the route I just created... again the whole world map. Still love the site though, will be awesome if you can fix this bug. Thanks By MC on 21st May 2021

Probably no one else on this entire planet has measured and calculated more points and distances on the good old previous daft logic tool version than me. Now I recommend using Google Maps Distance Calculator for the purposes which were earlier feasible thanks to the good old previous daft logic tool version, even though the Google Maps Distance Calculator is unfortunately far from the previous easiness of the good old daft logic tool version. I would love to stay faithful to daft logic, however it unfortunately isn't possible and it's time to say goodbye !!!! By JIRKA, OSTRAVA, CZECH REPUBLIC on 2nd March 2021

I have used your site for many years and have always loved it! the new updates are a step backward. My farm is now obscured with cloud cover and the resolution is far from what it once was. I will be looking for a new site to use now. My zip code is 46392. By DavidD on 23rd February 2021

Hi Robert, unfortunately not. The old map interface came at a significant cost to us that was not feasible to maintain going forward. It is understood the loss of high resolution is a disappointment. By Daft Logic on 16th February 2021

3D Distance Calculator

Use this calculator to find the distance between two points on a 3D coordinate space.

Distance Based on Latitude and Longitude

Use this calculator to find the shortest distance (great circle/air distance) between two points on the Earth's surface.

• Degree-Minute-Second

Distance on Map

Click the map below to set two points on the map and find the shortest distance (great circle/air distance) between them. Once created, the marker(s) can be repositioned by clicking and holding, then dragging them.

Distance in a coordinate system

Distance in a 2D coordinate plane:

The distance between two points on a 2D coordinate plane can be found using the following distance formula

d = √ (x 2 - x 1 ) 2 + (y 2 - y 1 ) 2

where (x 1 , y 1 ) and (x 2 , y 2 ) are the coordinates of the two points involved. The order of the points does not matter for the formula as long as the points chosen are consistent. For example, given the two points (1, 5) and (3, 2), either 3 or 1 could be designated as x 1 or x 2 as long as the corresponding y-values are used:

Using (1, 5) as (x 1 , y 1 ) and (3, 2) as (x 2 , y 2 ):

Using (3, 2) as (x 1 , y 1 ) and (1, 5) as (x 2 , y 2 ):

In either case, the result is the same.

Distance in a 3D coordinate space:

The distance between two points on a 3D coordinate plane can be found using the following distance formula

d = √ (x 2 - x 1 ) 2 + (y 2 - y 1 ) 2 + (z 2 - z 1 ) 2

where (x 1 , y 1 , z 1 ) and (x 2 , y 2 , z 2 ) are the 3D coordinates of the two points involved. Like the 2D version of the formula, it does not matter which of two points is designated (x 1 , y 1 , z 1 ) or (x 2 , y 2 , z 2 ), as long as the corresponding points are used in the formula. Given the two points (1, 3, 7) and (2, 4, 8), the distance between the points can be found as follows:

Distance between two points on Earth's surface

There are a number of ways to find the distance between two points along the Earth's surface. The following are two common formulas.

Haversine formula:

The haversine formula can be used to find the distance between two points on a sphere given their latitude and longitude:

In the haversine formula, d is the distance between two points along a great circle, r is the radius of the sphere, ϕ 1 and ϕ 2 are the latitudes of the two points, and λ 1 and λ 2 are the longitudes of the two points, all in radians.

The haversine formula works by finding the great-circle distance between points of latitude and longitude on a sphere, which can be used to approximate distance on the Earth (since it is mostly spherical). A great circle (also orthodrome) of a sphere is the largest circle that can be drawn on any given sphere. It is formed by the intersection of a plane and the sphere through the center point of the sphere. The great-circle distance is the shortest distance between two points along the surface of a sphere.

Results using the haversine formula may have an error of up to 0.5% because the Earth is not a perfect sphere, but an ellipsoid with a radius of 6,378 km (3,963 mi) at the equator and a radius of 6,357 km (3,950 mi) at a pole. Because of this, Lambert's formula (an ellipsoidal-surface formula), more precisely approximates the surface of the Earth than the haversine formula (a spherical-surface formula) can.

Lambert's formula:

Lambert's formula (the formula used by the calculators above) is the method used to calculate the shortest distance along the surface of an ellipsoid. When used to approximate the Earth and calculate the distance on the Earth surface, it has an accuracy on the order of 10 meters over thousands of kilometers, which is more precise than the haversine formula.

Lambert's formula is as follows:

where a is the equatorial radius of the ellipsoid (in this case the Earth), σ is the central angle in radians between the points of latitude and longitude (found using a method such as the haversine formula), f is the flattening of the Earth, and X and Y are expanded below.

Where P = (β 1 + β 2 )/2 and Q = (β 2 - β 1 )/2

In the expressions above, β 1 and β 1 are reduced latitudes using the equation below:

tan(β) = (1 - f)tan(ϕ)

where ϕ is the latitude of a point.

Note that neither the haversine formula nor Lambert's formula provides an exact distance because it is not possible to account for every irregularity on the surface of the Earth.

Distance Calculator

What is distance, the distance formula for euclidean distance, distance to any continuous structure, distance to a line and between 2 lines, how to find the distance using our distance calculator, driving distance between cities: a real-world example, distance from earth to moon and sun - astronomical distances, distance beyond length.

Have you ever wanted to calculate the distance from one point to another, or the distance between cities? Have you ever wondered what the distance definition is? We have all these answers and more, including a detailed explanation of how to calculate the distance between any two objects in 2D space. As a bonus, we have a fascinating topic on how we perceive distances (for example as a percentage difference ); we're sure you'll love it!

Before we get into how to calculate distances, we should probably clarify what a distance is . The most common meaning is the 1D space between two points. This definition is one way to say what almost all of us think of distance intuitively, but it is not the only way we could talk about distance. You will see in the following sections how the concept of distance can be extended beyond length, in more than one sense that is the breakthrough behind Einstein's theory of relativity.

If we stick with the geometrical definition of distance we still have to define what kind of space we are working in . In most cases, you're probably talking about three dimensions or less, since that's all we can imagine without our brains exploding. For this calculator, we focus only on the 2D distance (with the 1D included as a special case). If you are looking for the 3D distance between 2 points we encourage you to use our 3D distance calculator made specifically for that purpose.

To find the distance between two points, the first thing you need is two points, obviously . These points are described by their coordinates in space. For each point in 2D space, we need two coordinates that are unique to that point. If you wish to find the distance between two points in 1D space you can still use this calculator by simply setting one of the coordinates to be the same for both points . Since this is a very special case, from now on we will talk only about distance in two dimensions.

The next step, if you want to be mathematical, accurate, and precise , is to define the type of space you're working in. No, wait, don't run away! It is easier than you think. If you don't know what space you're working in or if you didn't even know there is more than one type of space, you're most likely working in Euclidean space . Since this is the "default" space in which we do almost every geometrical operation, and it's the one we have set for the calculator to operate on. Let's dive a bit deeper into Euclidean space , what is it, what properties does it have and why is it so important?

The Euclidean space or Euclidean geometry is what we all usually think of 2D space is before we receive any deep mathematical training in any of these aspects. In Euclidean space, the sum of the angles of a triangle equals 180º and squares have all their angles equal to 90º; always. This is something we all take for granted, but this is not true in all spaces . Let's also not confuse Euclidean space with multidimensional spaces. Euclidean space can have as many dimensions as you want, as long as there is a finite number of them, and they still obey Euclidean rules .

We do not want to bore you with mathematical definitions of what is a space and what makes the Euclidean space unique, since that would be too complicated to explain in a simple distance calculator. However, we can try to give you some examples of other spaces that are commonly used and that might help you understand why Euclidean space is not the only space. Also, you will hopefully understand why we are not going to bother calculating distances in other spaces .

The first example we present to you is a bit obscure, but we hope you can excuse us, as we're physicists , for starting with this very important type of space: Minkowski space . The reason we've selected this is because it's very common in physics , in particular it is used in relativity theory, general relativity and even in relativistic quantum field theory. This space is very similar to Euclidean space, but differs from it in a very crucial feature: the addition of the dot product, also called the inner product (not to be confused with the cross product).

Both the Euclidean and Minkowski space are what mathematicians call flat space . This means that space itself has flat properties; for example, the shortest distance between any two points is always a straight line between them (check the linear interpolation calculator). There are, however, other types of mathematical spaces called curved spaces in which space is intrinsically curved and the shortest distance between two points is no a straight line.

This curved space is hard to imagine in 3D, but for 2D we can imagine that instead of having a flat plane area, we have a 2D space, for example, curved in the shape of the surface of a sphere. In this case, very strange things happen . The shortest distance from one point to another is not a straight line, because any line in this space is curved due to the intrinsic curvature of the space. Another very strange feature of this space is that some parallel lines do actually meet at some point . You can try to understand it by thinking of the so-called lines of longitude that divide the Earth into many time zones and cross each other at the poles.

It is important to note that this is conceptually VERY different from a change of coordinates . When we take the standard x , y , z x, y, z x , y , z coordinates and convert into polar, cylindrical, or even spherical coordinates, but we will still be in Euclidean space. When we talk about curved space, we are talking about a very different space in terms of its intrinsic properties . In spherical coordinates, you can still have a straight line and distance is still measured in a straight line, even if that would be very hard to express in numbers.

Coming back to the Euclidean space, we can now present you with the distance formula that we promised at the beginning . The distance formula is

which relates to the Pythagorean Theorem, which states that a 2 + b 2 = c 2 a^2+b^2=c^2 a 2 + b 2 = c 2 . Here, a a a and b b b are legs of a right triangle and c c c is the hypotenuse. Suppose that two points, ( x 1 , y 1 ) (x_1, y_1) ( x 1 ​ , y 1 ​ ) and ( x 2 , y 2 ) (x_2, y_2) ( x 2 ​ , y 2 ​ ) , are coordinates of the endpoints of the hypotenuse . Then ( x 2 − x 1 ) 2 (x_2 - x_1)^2 ( x 2 ​ − x 1 ​ ) 2 in the distance equation corresponds to a 2 a^2 a 2 and ( y 2 − y 1 ) 2 (y_2 - y_1)^2 ( y 2 ​ − y 1 ​ ) 2 corresponds to b 2 b^2 b 2 . Since c = a 2 + b 2 c = \sqrt{a^2 + b^2} c = a 2 + b 2 ​ , you can see why this is just an extension of the Pythagorean theorem .

The distance formula we have just seen is the standard Euclidean distance formula , but if you think about it, it can seem a bit limited. We often don't want to find just the distance between two points. Sometimes we want to calculate the distance from a point to a line or to a circle. In these cases, we first need to define what point on this line or circumference we will use for the distance calculation, and then use the distance formula that we have seen just above.

Here is when the concept of perpendicular line becomes crucial. The distance between a point and a continuous object is defined via perpendicularity. From a geometrical point of view, the first step to measure the distance from one point to another, is to create a straight line between both points, and then measure the length of that segment . When we measure the distance from a point to a line, the question becomes "Which of the many possible lines should I draw?". In this case the answer is: the line from the point that is perpendicular to the first line . This distance will be zero in the case in which the point is a part of the line. For these 1D cases, we can only consider the distance between points, since the line represents the whole 1D space .

This imposes restrictions on how to compute distances in some interesting geometrical instances. For example, we could redefine the concept of height of a triangle to be simply the distance from one vertex to the opposing side of the triangle. In this case, the triangle area is also redefined in terms of distance, since the area is a function of the height of the triangle.

Let's look at couple examples in 2D space. To calculate the distance between a point and a straight line we could go step by step (calculate the segment perpendicular to the line from the line to the point and the compute its length) or we could simply use this 'handy-dandy' equation :

where the line is given by A x + B y + C = 0 Ax+By+C = 0 A x + B y + C = 0 and the point is defined by ( x 1 , y 1 ) (x_1, y_1) ( x 1 ​ , y 1 ​ ) .

The only problem here is that a straight line is generally given as y = m x + b y=mx+b y = m x + b , so we would need to convert this equation to the previously show form:

so we can see that A = m A=m A = m , B = − 1 B=-1 B = − 1 and C = b C=b C = b . This leaves the previous equation with the following values:

For the distance between 2 lines, we just need to compute the length of the segment that goes from one to the other and is perpendicular to both. Once again, there is a simple formula to help us :

if the lines are A 1 x + B 1 y + C 1 = 0 A_1x+B_1y+C_1=0 A 1 ​ x + B 1 ​ y + C 1 ​ = 0 and A 2 x + B 2 y + C 2 = 0 A_2x+B_2y+C_2=0 A 2 ​ x + B 2 ​ y + C 2 ​ = 0 . We can also convert to slope intercept form and obtain:

for lines y = m 1 x + b 1 y=m_1x+b_1 y = m 1 ​ x + b 1 ​ and y = m 2 x + b 2 y=m_2x+b_2 y = m 2 ​ x + b 2 ​ .

Notice that both line needs to be parallel since otherwise the would touch at some point and their distance would then be d = 0 d=0 d = 0 . That's the reason the formulas omit most of the subscripts since for parallel lines: A 1 = A 2 = A A_1=A_2=A A 1 ​ = A 2 ​ = A and B 1 = B 2 = B B_1=B_2=B B 1 ​ = B 2 ​ = B while in slope intercept form parallel lines are those for which m 1 = m 2 = m m_1=m_2=m m 1 ​ = m 2 ​ = m .

As we have mentioned before, distance can mean many things , which is why we have provided a few different options for you in this calculator. You can calculate the distance between a point and a straight line, the distance between two straight lines (they always have to be parallel), or the distance between points in space. When it comes to calculating the distances between two point, you have the option of doing so in 1, 2, 3, or 4 dimensions. We know, we know, 4 dimensions sounds scary , but you don't need to use that option. And you can always learn more about it by reading some nice resources and playing around with the calculator. We promise it won't break the Internet or the universe.

We have also added the possibility for you to define 3 different points in space, from which you will obtain the 3 pairs of distances between them, so, if you have more than two points, this will save you time. The number of dimensions you are working in will determine the number of coordinates that describe a point, which is why, as you increase the number of dimensions, the calculator will ask for more input values.

Even though using the calculator is very straightforward, we still decided to include a step-by-step solution. This way you can get acquainted with the distance formula and how to use it (as if this was the 1950's and the Internet was still not a thing). Now let's take a look at a practical example: How to find the distance between two points in 2-D.

Suppose you have two coordinates, ( 3 , 5 ) (3, 5) ( 3 , 5 ) and ( 9 , 15 ) (9, 15) ( 9 , 15 ) , and you want to calculate the distance between them. To calculate the 2-D distance between these two points, follow these steps:

• Input the values into the formula: ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} ( x 2 ​ − x 1 ​ ) 2 + ( y 2 ​ − y 1 ​ ) 2 ​ .
• In the formula, subtract the values in the parentheses.
• Square both quantities in the parentheses.
• Add the results.
• Take the square root.
• Use the distance calculator to check your results.

Working out the example by hand, you get:

which is equal to approximately 11.66 11.66 11.66 . Note, that when you take the square root, you will get a positive and negative result, but since you are dealing with distance, you are only concerned with the positive result . The calculator will go through this calculations step by step to give you the result in exact and approximate formats.

Let's take a look of one of the applications of the distance calculator. Suppose you are traveling between cities A and B, and the only stop is in city C, with a route A to B perpendicular to route B to C. We can determine the distance from A to B, and then, knowing the gas price, determine fuel cost , fuel used and cost per person while traveling. The gas calculator, that you can find on our site, can ease that for you.

The difficulty here is to calculate the distances between cities accurately . A straight line (like what we use in this calculator) can be a good approximation, but it can be quite off if the route you're taking is not direct but takes some detour, maybe to avoid mountains or to pass by another city. In that case, just use Google maps or any other tool that calculates the distance along a path not just the distance from one point to another as the crow flies.

Our calculator can give proper measurements and predictions for distances between objects, not the length of a path . With this in mind, there are still multiple scenarios in which you might actually be interested in the distance between objects, regardless of the path you would have to take. One such example is the distance between astronomical objects .

When we look at a distance within our Earth, it is hard to go far without bumping into some problems , from the intrinsic curvature of this space (due to the Earth curvature being non-zero) to the limited maximum distance between two points on the Earth. It is because of this, and also because there is a whole universe beyond our Earth , that distances in the universe are of big interest for many people. Since we have no proper means of interplanetary traveling, let alone interstellar travels, let's focus for now on the actual Euclidean distance to some celestial objects. For example the distance from the Earth to the Sun, or the distance from the Earth to the Moon.

These distances are beyond imaginable for our ape-like brains. We struggle to comprehend the size of our planet, never mind the vast, infinite universe. This is so difficult that we need to use either scientific notation or light years, as a unit of distance for such long lengths . The longest trips you can do on Earth are barely a couple thousand kilometers, while the distance from Earth to the Moon, the closest astronomical object to us, is 384,000 km . On top of that, the distance to our closest star, that is the distance from Earth to the Sun , is 150,000,000 km or a little over 8 light minutes .

When you compare these distances with the distance to our second nearest star (Alpha Centauri) , which is 4 light years , suddenly they start to look much smaller. If we want to go even more ridiculous in comparison we can always think about a flight from New York to Sydney, which typically takes more than 20 h and it's merely over 16,000 km , and compare it with the size of the observable universe, which is about 46,600,000,000 light years !

Here, we have inadvertently risen a fascinating point , which is that we measure distances not in length but in time. Thus, we extend the notion of distance beyond its geometrical sense. We will explore this possibility in the next section as we speak about the importance and usefulness of distance beyond the purely geometrical sense . This is a very interesting path to take and is mostly inspired by the philosophical need to extend every concept to have a universal meaning, as well as from the obvious physical theory to mention, when talking about permutations of the space and time, or any other variable that can be measured .

Typically, the concept of distance refers to the geometric Euclidean distance and is linked to length. However, you can extend the definition of distance to mean just the difference between two things , and then a world of possibilities opens up. Suddenly one can decide what is the best way to measure the distance between two things and put it in terms of the most useful quantity. A very simple step to take is to think about the distance between two numbers, which is nothing more than the 1D difference between these numbers . To obtain it, we simply subtract one from the other and the result would be the difference, a.k.a. the distance.

We could jump from this numerical distance to, for example, difference or distance in terms of the percentage difference, which in some cases might provide a better way of comparison . This is still just one level of abstraction in which we simply remove the units of measurement. But what if we were to use different units altogether?

By extending the concept of distance to mean something closer to difference , we can calculate the difference between two temperatures, or other related quantity like pressure. But we don't need to get really extreme, let's see how two points can be separated by a different distance, depending on the assumptions made . Coming back to the driving distance example, we could measure the distance of the journey in time, instead of length. In this case, we need an assumption to allow such translation; namely the way of transport.

There is a big difference in the time taken to travel 10 km by plane versus the time it takes by car . Sometimes, however, the assumption is clear and implicitly agreed on, like when we measure the lightning distance in time which we then convert to length. This brings up an interesting point, that the conversion factor between distances in time and length is what we call "speed" or "velocity" (remember they are not exactly the same thing). Truth be told, this speed doesn't have to be constant as exemplified by accelerated motions such as that of a free fall under gravitational force, or the one that links stopping time and stopping distance via the breaking force and drag or, in very extreme cases, via the force of a car crash.

Another place where you can find weird units of distance are in solid state physics, where the distance a particle travels inside of a material is often expressed as an average of interactions or collisions. This distance is linked to length by using the mean free path, which is the mean distance (in length) a particle travels between interactions. If we want to get even more exotic we can think about the distance from the present value to the future value of something like a car.

We don't want to, however, make anyone's brain explode, so please don't think too hard about this . Just take this calculator and use it for length-based distance in 2D space. You can always return to this philosophical view on distances if you ever find yourself bored!

How to find the distance between two points?

To find the distance between two points we will use the distance formula: √[(x₂ - x₁)² + (y₂ - y₁)²]:

• Get the coordinates of both points in space.
• Subtract the x-coordinates of one point from the other, same for the y components.
• Square both results separately.
• Sum the values you got in the previous step.
• Find the square root of the result above.

If you think this is too much effort, you can simply use the Distance Calculator from Omni

Is distance a vector?

Distance is not a vector . The distance between points is a scalar quantity, meaning it is only defined by its value. However, the displacement is a vector with value and direction. So the distance between A and B is the same as the distance from B to A, but the displacement is different depending on their order.

What is a klick in distance?

Click is slang for a kilometer which is 0.62 miles. It is actually written with "k" (Klick) as it is derived from the word kilometer. It is commonly used in the military and motorcyclists.

What is the distance formula?

The distance formula is: √[(x₂ - x₁)² + (y₂ - y₁)²] . This works for any two points in 2D space with coordinates (x₁, y₁) for the first point and (x₂, y₂) for the second point. You can memorize it easily if you notice that it is Pythagoras theorem and the distance is the hypothenuse, and the lengths of the catheti are the difference between the x and y components of the points.

How to find the distance of a vector?

The distance of a vector is its magnitude . If you know its components:

• Take each of the components of the vector and square them.
• Sum them up.
• Find the square root of the previous result.
• Enjoy the good work!

If you know its polar representation , it will be a number and an angle. That number is the magnitude of the vector, which is its distance.

What is the SI unit of distance?

The SI unit of distance is the meter , abbreviated to "m". A meter is approximately 3.28 feet. Other common units in the International System of units are the centimeter (one one-hundredth of a meter, or 0.39 inches) and the kilometer (one thousand meters or 0.62 miles), among others.

What is the distance from A to B?

The distance from A to B is the length of the straight line going from A to B. The distance from B to A is the same as the distance from A to B because distance is a scalar

What is the dimension of distance?

Distance is a measure of one-dimensional space. The distance between two points is the shortest length of 1D space between them. If you divide distance over time you will get speed, which has dimensions of space over time.

Is light-year time or distance?

A light-year is a measurement of distance. It is 9.461×10 12 kilometers or 5.879×10 12 miles, which is the distance traveled by a ray of light in a perfect vacuum over the span of a year.

How to solve for distance with velocity and time?

The velocity and the moving time of an object you can calculate the distance:

• Make sure the speed and time have compatible units (miles per hour and hours, meter per second, and seconds…).
• If they aren't, convert them to the necessary units.
• Multiply the velocity by the time .
• The result should be the distance traveled in whichever length units your speed was using!

    Speed, Distance & Time Calculation

In order to use the above speed, distance & time calculator, or do such math on your own, you will need to know two out of three metrics: speed, distance, time. You will need to convert the metrics to the same time and distance units, e.g. miles, kilometers, meters, yards, feet, and hours, minutes or seconds. For example, if you have speed in mph (miles per hour), time should also be in hours. If you have distance in kilometers, then speed should also be in km/h (kilometers per hour).

The unit of the result will depend on the units you input, but our speed calculator will conveniently display additional units where appropriate.

    Average Speed formula

The formula for average speed, also called average velocity in physics and engineering, is:

where v is the velocity, d is the distance, and t is the time, so you can read it as Speed = Distance / Time . As noted above, make sure you convert the units appropriately first, or use our speed calculator which does that automatically. The resulting unit will depend on the units for both time and distance, so if your input was in miles and hours, the speed will be in mph. If it was in meters and seconds, it will be in m/s (meters per second).

Example: If you took a plane from New York to Los Angeles and the flight was 5 hours of air time, what was the speed of the plane, given that the flight path was 2450 miles? The answer is 2450 / 5 = 490 mph (miles per hour) average speed. If you want the result in km/h, you can convert from miles to km to get 788.58 km/h.

    Distance formula

The formula for distance, if you know time (duration) and the average speed, is:

Example: If a truck travelled at an average speed of 80 km per hour for 4 hours, how many miles did it cover in that time? To find the miles covered, first, calculate 80 * 4 = 320 km, then convert km to miles by dividing by 1.6093 or by using our km to miles converter to get the answer: 198.84 miles.

    Duration (Time) formula

The time, or more precisely, the duration of the trip, can be calculated knowing the distance and the average speed using the formula:

where d is the distance travelled, v is the speed (velocity) and t is the time, so you can read it as Time = Distance / Speed . Make sure you convert the units so both their distance and time components match, or use our trip duration calculator above which will handle conversions automatically. For example, if you have distance in miles and speed in km/h, you will need to convert speed to mph or distance to kilometers. The time unit of the result will match the time unit of the speed measure, so if it is measured in something per hour, the result will be in hours. If it is measured in some unit per second, the result will be in seconds.

Example: If a train can travel 500 miles with an average speed of 50 miles per hour, how long it would take it to complete a 500-mile route? To find the answer, use the formula and substitute the values, resulting in 500 / 50 = 10 hours.

    How to calculate the average speed of a car?

Say you travelled a certain distance with a car or another vehicle and you want to calculate what its average speed was. The easiest way to do that would be by using the calculator above, but if you prefer, you can also do the math yourself. Either way, you need to know the distance to a satisfactory approximation, for which you can use a map (e.g. Google Maps) to measure the distance from point to point. Make sure you measure closely to the path you took, and not via a straight line, unless you travelled by air in which case that would be a good approximation. Of course, having a GPS reading of the distance would be more precise. Then you need to know the travel time. Make sure you subtract any rests or stops you made from the total trip duration.

If the total distance travelled was 500 miles and the time it took you was 5 hours, then your average speed was 500 / 5 = 100 miles per hour (mph). If the distance was 300 kilometers and it took you 5 hours to cover it, your speed was 300 / 5 = 60 km/h (kilometers per hour).
