kg/m³
kilogram per cubic meter
Densityexact by definition
The kilogram per cubic metre is the coherent SI unit of density, formed directly from the base units, so its factor is 1 by construction. Liquid water near 4 °C is very close to 1000 kg/m³, dry air at sea level about 1.2 kg/m³, and structural steel about 7850 kg/m³.
