Metre per second ( U.S. spelling: meter 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, m s, m/s, or , 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".

Suddenly I was very aware of the vulnerability of my nose and front teeth, should they happen to come into contact with the granite of Porteniel's pavements at any velocity above quite a small fraction of a metre per second.
While he had said it was 'merely' a job of matching velocities, it required very careful 'puffs' of his thrusters to slow the KDM down and introduce a rate of closure with the satellite of about one-quarter to one-half metre per second.
