1 m/s equals 3.6 km/h. To convert m/s to km/h, multiply the value by 3.6; divide by 3.6 to convert back. Enter any number above and the result appears instantly — free and entirely in your browser.
How do you convert m/s to km/h?
The conversion formula is km/h = m/s × 3.6. The conversion factor is fixed by definition, so the result is always exact.
m/s to km/h conversion table
| m/s | km/h |
|---|---|
| 10 m/s | 36 km/h |
| 30 m/s | 108 km/h |
| 50 m/s | 180 km/h |
| 80 m/s | 288 km/h |
| 100 m/s | 360 km/h |
| 130 m/s | 468 km/h |
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.
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.
Why convert m/s to km/h?
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.
