If you need to change from metres per second to kilometres per hour, use our accurate speed converter! With many more available, they are simple to use.

As two different units of speed, **metres per second** and **kilometres per hour** are used for different contexts. As a measurement of slower speeds, m/s can be used as a quantity of movement and as a velocity when it is squared to become m/s². Used more conventionally,** km/h can be visibily seen on road signs for car speeds**. Above you will find our **m/s to km/h conversion tool**, along with many more speed converters.

## How to use the Converter from m/s to km/h?

Simple to use, our **metres per second – kilometres per hour converter** will help with your calculations. Enter the amount of m/s you need to change and click “convert” to be given the equivalent in km/h. To calculate the other way, convert kilometres per hour to metres per second.

## Formula to Convert m/s – km/h

In mathematical terms, the equation for this speed conversion is shown below should you wish to do it by hand, or if you would like to know how it’s done. As some examples, 23 m/s = 82.8 km/h and 41 m/s = 147.6 km/h

**[number of] metres per second x 3.6 = [number of] kilometres per hour**

## When to use m/s

As a unit of speed used to measure slower speeds, **metres per second** are used less commonly in everyday situations. The most common industry to use m/s is in astronomy, however, sometimes m/s is still too slow so km/s is used. Metres per second are defined by the amount of distance travelled in metres, divided by the time it took in seconds. View our **m/s to km/h calculator**.

## When to use km/h?

**Kilometres per hour** is the most common unit of speed that is used worldwide and is spelt as kilometers per hour in American English. It is found on road signs and in car speedometers with several different abbreviations such as km/h, the official one, kph, kmph and km/hr. Use our **m/s to km/h speed converter** above.
