How to convert metres per second to kilometres per hour
km/h = m/s × 3.6
Example: 5 m/s × 3.6 = 18 km/h

About these units
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.
Kilometers per Hour (km/h): Kilometres per hour (km/h) is the speed unit on road signs and speedometers in most of the world.
Frequently asked questions
How many kilometres per hour are in 1 metre per second?
1 metre per second (m/s) equals 3.6 kilometres per hour (km/h).
How do I convert m/s to km/h?
Multiply the value in metres per second by 3.6. For example, 5 m/s × 3.6 = 18 km/h.
How do I convert kilometres per hour back to metres per second?
Multiply by 0.2777777778 (or divide by 3.6). 1 km/h = 0.2777777778 m/s.
What does m/s mean?
Metres per second (m/s) is the SI unit of speed, used in science and for wind speed in some forecasts.
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.
