### FAQ about Kilometer/Second to Kilometer/Hour Conversion

1 kilometer/second (km/s) is equal to 3600 kilometer/hour (km/h).

1km/s = 3600km/h

The speed v in kilometer/hour (km/h) is equal to the speed v in kilometer/second (km/s) times 3600, that conversion formula:

v(km/h) = v(km/s) × 3600

One Kilometer/Second is equal to 3600 Kilometer/Hour:

1km/s = 1km/s × 3600 = 3600km/h

One Kilometer/Hour is equal to 0.00028 Kilometer/Second:

1km/h = 1km/h × 0.00028 = 0.00028km/s

v(km/h) = 5(km/s) × 3600 = 18000km/h
