  1. 1 m/s = 3.6 km/h
  2. 1 × 3.6 = 3.6 km/h

How to convert meters per second to kilometers per hour

1 m/s = 3.6 km/h, so multiply by 3.6 to go from meters per second to kilometers per hour. Going the other way, 1 km/h = 0.277777777778 m/s.

km/h = m/s × 3.6
m/s = km/h × 0.277777777778

Worked example:

1 m/s = 3.6 km/h
5 × 3.6 = 18 km/h
