m/s and km/h

Convert speed between meters per second and kilometers per hour (1 m/s = 3.6 km/h).

FAQ

What factor converts m/s to km/h?

1 m/s = 3.6 km/h, so km/h = m/s × 3.6 and m/s = km/h ÷ 3.6. Only non‑negative speeds are accepted in validation.

Does the decimal separator matter?

This calculator uses plain decimal numbers. If a result looks wrong, check whether you used a comma instead of a dot (or vice versa) where the field expects one.
