How to convert km/h to m/s
Divide the value in km/h by 3.6 to get m/s. As a formula: m/s = km/h ÷ 3.6
Good to know
Divide km/h by 3.6 for m/s: 100 km/h is 27.78 m/s and 36 km/h is exactly 10 m/s. Physics formulas want m/s, so convert a speed limit before working out acceleration or stopping distance.
