Convert meters per second (m/s) to km/h, mph, knots, and Mach.
Calculator
The meter per second (m/s) is the SI unit of speed. An object moving at 1 m/s travels one meter in one second.
Common m/s conversions
- 1 m/s = 3.6 km/h — multiply by 3.6 to convert to kilometers per hour.
- 1 m/s ≈ 2.237 mph — multiply by 2.237 to convert to miles per hour.
- 1 m/s ≈ 1.944 knots — multiply by 1.944 to convert to nautical miles per hour.
- 1 m/s ≈ 0.00292 Mach — at sea level and 20 °C.
Meters per second is the standard unit in physics, engineering, and scientific research. In everyday contexts, speed is more often expressed in km/h or mph depending on the country.
