**Metre per second** is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.

The SI unit symbols are m·s^{−1}, m s^{−1}, or m/s, sometimes (unofficially) abbreviated as "mps". Where metres per second are several orders of magnitude too slow to be convenient, such as in astronomical measurements, velocities may be given in **kilometres per second**, where 1 km/s is 1000 metres per second, sometimes unofficially abbreviated as "kps".
