Meters per second to kilometers per hour
Type a value in m/s to get it in km/h instantly.
That's 1.12× as fast as a bullet train, while an airliner is 2.5× faster. In one minute you'd cover 6 km.
Convert the other way: km/h to m/s
What it means
How fast is that?
Reference speeds are typical values. Mach uses the speed of sound in dry air at 20 °C (343 m/s).
The math
How to convert m/s to km/h
To convert meters per second to kilometers per hour, multiply by 3.6.
Example: 100 m/s × 3.6 = 360 km/h.
In the other direction, 1 km/h = 0.277778 m/s.
