1 km/s = 3600 km/h
1 × 3600 = 3600 km/h

How to convert kilometers per second to kilometers per hour

1 km/s = 3,600 km/h, so multiply by 3,600 to go from kilometers per second to kilometers per hour. Going the other way, 1 km/h = 0.000277777777778 km/s.

km/h = km/s × 3,600
km/s = km/h × 0.000277777777778

Worked example:

1 km/s = 3600 km/h
5 × 3600 = 18000 km/h
