  1. 1 km/h = 0.277777777778 m/s
  2. 1 × 0.277777777778 = 0.277777777778 m/s

How to convert kilometers per hour to meters per second

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

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

Worked example:

1 km/h = 0.277777777778 m/s
5 × 0.277777777778 = 1.38888888889 m/s
