m/s to km/h – convert metres per second to kilometres per hour
Convert m/s to km/h (metres per second to kilometres per hour) to turn physics results or treadmill speeds into familiar road-style numbers. This page opens the main speed converter with m/s → km/h pre-selected.
Open the interactive m/s → km/h converter:
Use main converter (m/s → km/h) or switch to km/h → m/sYou can also jump to mph and knots on the homepage. The Tool Hub gives you focus timers while studying mechanics.
Quick reference: m/s to km/h
Because m/s × 3.6 = km/h, the formula is: km/h = m/s × 3.6.
| m/s | km/h |
|---|---|
| 1 m/s | 3.6 km/h |
| 2 m/s | 7.2 km/h |
| 3 m/s | 10.8 km/h |
| 4 m/s | 14.4 km/h |
| 5 m/s | 18.0 km/h |
| 10 m/s | 36.0 km/h |
How to convert m/s to km/h
Simply multiply by 3.6:
km/h = m/s × 3.6
Examples:
- 4 m/s × 3.6 = 14.4 km/h
- 6 m/s × 3.6 = 21.6 km/h
- 12 m/s × 3.6 = 43.2 km/h
Where m/s → km/h is useful
- Turning calculated speeds in physics into everyday scale numbers.
- Understanding sprint or wind speeds printed in m/s but thinking in km/h.
- Checking whether a calculated speed exceeds a given road speed limit.
- Interpreting lab or experiment data reported in metres per second.

The converter treats metres per second as the base speed, so going between m/s, km/h and mph is always consistent.
