# Average Speed Calculator

Use this speed calculator to easily calculate the average speed of a vehicle: car, bus, train, bike, motorcycle, plane etc. with a given distance and travel time. Returns miles per hour, km per hour, meters per second, etc.

## Average Speed formula

The average speed calculation is simple: given the distance travelled and the time it took to cover that distance, you can calculate your speed using this formula:

**Speed = Distance / Time**

The metric unit of the result will depend on the units you put in. For example, if you measured distance in meters and time in seconds, your output would be ft/s. If distance was measured in miles and time in hours, then output will be in miles per hour (mph, mi/h), and so on for km/h, m/s, etc. - all supported by our average speed calculator.

## How to calculate the average speed of a car?

Let us say, for example, that you travelled a certain distance with your car and want to calculate its average speed. The easiest way to do that would be by using the speed calculator above, but if you prefer, you can also do the math yourself. Either way, you need to know the distance, for which you can use a map (e.g. Google Maps) to measure the distance from point to point (not via a straight line, unless you travelled by air in which case that would be a good approximation). 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 250 miles and the time it took you was 5 hours, then your average speed was 250 / 5 = 50 miles per hour (mph). If the distance was 200 kilometers and it took you 4 hours to cover it, your speed was 200 / 4 = 50 km/h (kilometers per hour).
