  2. 1 × 0.001 = 0.001 km/s

How to convert meters per second to kilometers per second

1 m/s = 0.001 km/s, so multiply by 0.001 to go from meters per second to kilometers per second. Going the other way, 1 km/s = 1,000 m/s.

km/s = m/s × 0.001
m/s = km/s × 1,000

Worked example:

1 m/s = 0.001 km/s
5 × 0.001 = 0.005 km/s
