What is km/h (km/h)?
Kilometres per hour (km/h) is the everyday speed unit for road traffic in most of the world: speedometers, speed limits and weather reports all use it.
What is m/s (m/s)?
Metres per second (m/s) is the SI unit of speed, used in physics and for wind speeds. One m/s equals exactly 3.6 km/h.
Why convert km/h to m/s?
Road speeds are posted in km/h in most countries but in mph in the US and UK; shipping and aviation use knots, physics and wind data use metres per second. Converting between them is routine for travel, sailing and sport.
One knot is exactly 1.852 km/h — one international nautical mile (1,852 m, standardised in 1929) per hour. And 100 km/h equals 62.137 mph or 27.778 m/s.
