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 |
