Kilogram per cubic metre is the SI measure of density and is represented as kg/m^{3}^{[1]}, where kg stands for kilogram and m^{3} stands for cubic metre. The kilogram was originally based on the mass of one litre of water, thus the density of water is about 1000 kg/m^{3}.
kg/m^{3} is sometimes equivalently written as kg m^{−3}.
To convert from g/cm^{3} to kg/m^{3}, divide by 1,000 for grams to kilograms conversion and multiply by 100^{3} (there are 100 cm for every 1 metre) for the cm^{3} to m^{3} conversion, hence 1 g/cm^{3} equals 1000 kg/m^{3}.
