Kilogram per cubic metre is the SI measure of density and is represented as kg/m³, where kg stands for kilogram and m³ stands for cubic metre. The density of water is about 1000 kg/m³ (and is exactly this at 277 K), since a cubic metre of water weighs about 1 megagram.

kg/m³ is sometimes equivalently written as kg m^-3.

To convert from g/cm³ to kg/m³, divide by 1,000 for grams to kilograms conversion and multiply by 100³ for the cm³ to m³ conversion, hence 1 g/cm³ equals 1000 kg/m³.
