Kilometers per hour to meters per second
Type a value in km/h to get it in m/s instantly.
That's 1.85× as fast as a galloping horse, while a cheetah is 1.08× faster. In one minute you'd cover 1.667 km.
Convert the other way: m/s to km/h
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 km/h to m/s
To convert kilometers per hour to meters per second, multiply by 0.277778.
Example: 100 km/h × 0.277778 = 27.7778 m/s.
In the other direction, 1 m/s = 3.6 km/h.

About these units
Kilometers per hour (km/h)
The kilometer per hour is the speed unit on road signs and speedometers in most of the world. 1 km/h is 1,000 meters in 3,600 seconds, about 0.278 m/s.
Meters per second (m/s)
The meter per second is the SI unit of speed, used in physics, engineering, athletics and wind forecasts. 1 m/s is exactly 3.6 km/h.
