Definition

SI

The SI unit of velocity is the metre per second $\mathrm m \ \mathrm s^{-1}$, or, less formally, $\mathrm m / \mathrm s$.

CGS

The CGS unit of velocity is the centimetre per second $\mathrm {cm} \ \mathrm s^{-1}$, or, less formally, $\mathrm {cm} / \mathrm s$.

FPS

The FPS unit of velocity is the foot per second $\mathrm f \ \mathrm s^{-1}$, or, less formally, $\mathrm f / \mathrm s$.
