m/s to km/h Converter

Multiply meters per second by 3.6 to get kilometers per hour.

10 m/s = 36 km/h

Convert kilometers per hour to meters per second instead

Formula

1 m/s = 3.6 km/h

kilometers per hour = meters per second × 3.6

Worked example

Convert 10 meters per second to kilometers per hour

  1. Multiply by 3.6
  2. 10 × 3.6 = 36

10 m/s = 36 km/h

Good to know

The factor 3.6 comes from 3,600 seconds per hour divided by 1,000 meters per kilometer. Weather services often give wind in m/s: 10 m/s is 36 km/h, a fresh breeze. An elite sprinter averages about 10 m/s over 100 m.
