SI symbols follow international notation. U.S. and Imperial measures are labelled separately where their values differ.
Centimetre Per Second (cm/s) and kilometre per hour (km/h) are units of speed. Use this page to convert in either direction.
| Centimetre Per Second (cm/s) | Kilometre Per Hour (km/h) |
|---|---|
| 1 cm/s | 0.036 km/h |
| 5 cm/s | 0.18 km/h |
| 10 cm/s | 0.36 km/h |
| 100 cm/s | 3.6 km/h |
