How to convert kilometers per hour to meters per second

m/s = km/h ÷ 3.6

Example: convert 8 kilometers per hour to meters per second.
8 km/h ÷ 3.6 = 2.222222222 m/s

The same relationship in reverse: 1 meter per second = 3.6 kilometers per hour, so you can also multiply by 0.2777777778. Need the other direction? Use the meters per second to kilometers per hour converter.

You will typically need this conversion for physics problems, sprinting and wind speed.

About the units

Kilometer Per Hour (km/h)

Used for road speed limits and car speedometers in most of the world. 1 km/h = 1/3.6 m/s.

Meter Per Second (m/s)

The SI unit of speed. Used in physics and for wind speed in many weather services.

Frequently asked questions
