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.

››Definition: Kilometer/hour

The kilometre per hour (American English: kilometer per hour) is a unit of both speed (scalar) and velocity (vector).

The km/h is the worldwide most commonly used speed unit on road signs and car speedometers.
