About Kilometers per Hour to Meters per Second
Kilometers per hour to meters per second converts the everyday road and weather speed unit into the SI unit used in physics. Dividing by 3.6 turns a km/h figure into meters per second.
To convert kilometers per hour to meters per second, divide the value by 3.6 (or multiply by 0.2777778). m/s = km/h ÷ 3.6.
For example, 90 km/h ÷ 3.6 = 25 m/s. A car travelling 90 km/h covers 25 meters every second.
