Definition:Velocity/Unit

Definition
The units of measurement of velocity are as follows:


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


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

Thus we see:
 * $1 \ \mathrm m \ \mathrm s^{-1} = 10^2 \ \mathrm {cm} \ \mathrm s^{-1} = 100 \ \mathrm {cm} \ \mathrm s^{-1}$
