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 (there are 100cm for every 1 meter) for the cm³ to m³ conversion, hence 1 g/cm³ equals 1000 kg/m³.
