Why do we have different units for the same physical quantity ?
The value of any given physical quantity may vary over a wide range, so that, different units for same physical quantity are required.
E.g. : Speed of a cycle can be measured in $\mathrm{m} / \mathrm{s}$, speed of a car can be measured in $\mathrm{km} / \mathrm{h}$ and speed of a satellite can be measured in $\mathrm{km} / \mathrm{s}$.
