The basic unit, or S.I. unit, of speed is m/s, or metres per second. This means that to cover a distance of 1 metre, the time required is 1 second. The SI unit of distance is the metre, and the SI unit of time is the second. Speed is measured as distance divided by time. Speed is a scalar quantity with only one direction and no magnitude.
