Meter per second ( unit symbol : m / s) is the derived unit of speed in the SI system of units . An object moving at a constant speed of 1 m / s travels a distance of one meter in one second .

In everyday life, many speeds are instead given in km / h . The conversion from m / s to km / h is done using the factor 3.6 km / h / m / s.

An easy to remember rule for quickly converting m / s to km / h is: "Times four, minus 10%".

Some speeds in m / s

pedestrian 1 m / s
cyclist 7 m / s
World record 100 meter run ( Usain Bolt , average speed) 10.44 m / s
Motor vehicle outside built-up areas (corresponds to 108 km / h) 30 m / s
Top speed of a Bugatti Veyron (corresponds to 407 km / h) 113 m / s
Top speed of an aluminum rotor blade of a model helicopter with a length of 700 mm 130 m / s
Airliner 250 m / s
Speed ​​of sound in air at 20 ° C (1,234.8 km / h) 343 m / s
Escape speed from earth 11,180 m / s
Average speed of the earth on its orbit around the sun 29,780 m / s
Speed ​​of the sun on its orbit around the center of the Milky Way 220,000 m / s
Speed ​​of the sun in relation to the cosmic background radiation 369,500 m / s
Speed ​​of light in vacuum ; according to the special theory of relativity, the highest speed with which information can be transmitted. 299,792,458 m / s
