1 meter per second = 3.6 kilometers per hour
How to convert meters per second to kilometers per hour
kilometers per hour = meters per second × 3.6
To convert meters per second to kilometers per hour, multiply the value by 3.6. To go back from kilometers per hour to meters per second, divide by the same number (or multiply by 0.2777777778).
Worked examples
- 5 m/s: 5 × 3.6 = 18 km/h
- 10 m/s: 10 × 3.6 = 36 km/h
- 12.4 m/s: 12.4 × 3.6 = 44.64 km/h
Multiply by 3.6. A speed of 10 m/s is 36 km/h, and 28 m/s is about 100 km/h.
