About these units
Kilometers per Hour (km/h): Kilometres per hour (km/h) is the speed unit on road signs and speedometers in most of the world.
Meters per Second (m/s): Metres per second (m/s) is the SI unit of speed, used in science and for wind speed in some forecasts.
Frequently asked questions
How many metres per second are in 1 kilometre per hour?
1 kilometre per hour (km/h) equals 0.2777777778 metres per second (m/s).
How do I convert km/h to m/s?
Multiply the value in kilometres per hour by 0.2777777778. For example, 5 km/h × 0.2777777778 = 1.388888889 m/s.
How do I convert metres per second back to kilometres per hour?
Multiply by 3.6 (or divide by 0.2777777778). 1 m/s = 3.6 km/h.
What does km/h mean?
Kilometres per hour (km/h) is the speed unit on road signs and speedometers in most of the world.
Conversion factors come from exact international definitions (NIST SP 811, BIPM) where they exist. Results show up to 10 significant digits. Need every speed unit at once? Use the Speed Converter.
