Definition:Density (Physics)/Units

Definition

 * The SI units of density are $\mathrm {kg} \ \mathrm m^{-3}$ (kilograms per cubic metre).


 * The CGS units of density are $\mathrm g \ \mathrm{cm}^{-3}$ or, less formally: $\mathrm g / \mathrm {cc}$ (grams per cubic centimetre).

Thus:
 * $1 \ \mathrm g \ \mathrm {cm}^{-3} = 1000 \ \mathrm {kg} \ \mathrm m^{-3}$
