As an example of a quantity involving mixed units, consider the important quantity called density. Density is defined to be mass per unit volume:

$\rho=\frac{M}{V}$

Here $\rho$ is the density of a body, $M$ is its mass, and $V$ is its volume. The SI units of density are $\mathrm{kg} / \mathrm{m}^{3}$ ; mass has SI units of $\mathrm{kg}$ , and volume has SI units of $\mathrm{m}^{3}$ .
