This category of measurement units is defined by the "speed" type, which is an SI derived quantity.

The SI derived unit for speed is the meter/second.

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. One metre per second is roughly the speed of an average person walking.
