kgm^-3

Explanation:

The SI unit of density is the kilogram per cubic meter [kg/m3]. The Gaussian unit of density is the gram per cubic centimeter which is equivalent to a gram per milliliter [1 g/cm3 = 1 g/ml]. One thousand kilograms per cubic meter equals one gram per cubic centimeter [1000 kg/m3 = 1 g/cm3].
