Kilogram per cubic metreSI measure of density and is represented as kg/mó, where kg stands for kilogram and mó stands for cubic metre. The density of water is about 1000 kg/mó, since a cubic metre of water weighs about a tonne.
"kg/mó" is sometimes equivalently written as "kg m-3".
To convert from g/cmó to kg/mó, multiply by 1000; divide by 1000 for the opposite conversion. A gram per litre is identical in value to kg/m3.
