  1. 1 km/h = 27.7777777778 cm/s
  2. 1 × 27.7777777778 = 27.7777777778 cm/s

How to convert kilometers per hour to centimeters per second

1 km/h = 27.7777777778 cm/s, so multiply by 27.7777777778 to go from kilometers per hour to centimeters per second. Going the other way, 1 cm/s = 0.036 km/h.

cm/s = km/h × 27.7777777778
km/h = cm/s × 0.036

Worked example:

1 km/h = 27.7777777778 cm/s
5 × 27.7777777778 = 138.888888889 cm/s
