Meters per Second to Kilometers per Hour (m/s to km/h) Converter
1 meter per second (m/s) = 3.6 kilometers per hour (km/h). To convert meters per second to kilometers per hour, multiply by 3.6: 25 m/s × 3.6 = 90 km/h. Also searched as metres per second to kilometres per hour.
Quick facts
- 1 m/s = 3.6 km/h
- 1 km/h = 0.277778 m/s
- Formula: km/h = m/s × 3.6
- Quick estimate: multiply by about 3.6
How to convert meters per second to kilometers per hour
- Take the value in meters per second.
- Multiply it by 3.6 (the number of kilometers per hour in one meter per second).
- Round the result to the precision you need.
Worked example: 25 m/s × 3.6 = 90 km/h.
To convert kilometers per hour back to meters per second, multiply by 0.277778, or divide by 3.6.
