Formulas

Core equations used by this calculator.

m/s → km/hkm/h = (m/s) · 3.6
km/h → m/sm/s = (km/h) / 3.6
iSI units unless noted.

How to use

1

Choose m/s → km/h or km/h → m/s

Pick the direction that matches your input.

2

Enter the speed

Value must be finite (typically ≥ 0).

3

Read the converted speed

km/h = (m/s) · 3.6.
