M/S to KM/H Converter
Useful for wind speeds, physics problems and sprint speeds given in meters per second.
1 m/s = 3.6 km/h
kilometers per hour
1 m/s = 3.6 km/h
How to convert meters per second to kilometers per hour
Multiply the number of meters per second by 3.6.
Formula
km/h = m/s × 3.6
Examples
- 5 m/s × 3.6 = 18 km/h
- 12 m/s × 3.6 = 43.2 km/h
- 343 m/s × 3.6 = 1,234.8 km/h

About meters per second
Meters per second is the SI unit of speed. Physics problems use it, and many weather services report wind speed in m/s.
About kilometers per hour
Kilometers per hour is the unit on speed-limit signs and speedometers in most of the world. 1 km/h equals 1/3.6 m/s, or about 0.278 m/s.
Frequently asked questions
How many kilometers per hour are in one meter per second?
One meter per second equals 3.6 kilometers per hour.
How do I convert meters per second to kilometers per hour?
Multiply the number of meters per second by 3.6. For example: 12 m/s × 3.6 = 43.2 km/h.
How many meters per second are in one kilometer per hour?
One kilometer per hour equals 0.2778 meters per second.
Is the m/s to km/h conversion exact?
Yes. The factor follows directly from the official definitions of both units, so the only rounding is in how many decimals are displayed.
