How to convert centimeters per second to kilometers per second

1 cm/s = 1 × 10⁻⁵ km/s, so multiply by 1 to go from centimeters per second to kilometers per second. Going the other way, 1 km/s = 100,000 cm/s.

km/s = cm/s × 1
cm/s = km/s × 100,000

Worked example:

1 cm/s = 1e-5 km/s
5 × 1e-5 = 5e-5 km/s
