  2. 1 × 100000 = 100000 cm/s

How to convert kilometers per second to centimeters per second

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

cm/s = km/s × 100,000
km/s = cm/s × 1

Worked example:

1 km/s = 100000 cm/s
5 × 100000 = 500000 cm/s
