I'm feeling lucky, show me some random units.

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.

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.
