km/h to m/s Converter

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

36 km/h = 10 m/s

Convert meters per second to kilometers per hour instead

Formula

1 km/h = 0.2777777778 m/s

meters per second = kilometers per hour ÷ 3.6

Worked example

Convert 90 kilometers per hour to meters per second

  1. Divide by 3.6
  2. 90 ÷ 3.6 = 25

90 km/h = 25 m/s

Good to know

Physics formulas use SI units, so convert speeds to m/s before calculating kinetic energy or stopping distances. At 90 km/h a car covers 25 m every second — a useful fact for understanding following distances.
