Density Converter

Density across kilograms per cubic metre, grams per cubic centimetre and pounds per cubic foot. Water is one gram per cubic centimetre, which makes it the reference everything else is judged against.

Also called: g/cm3 to kg/m3, specific gravity converter.

Result

1,000

1 Gram per cubic centimetre is 1,000 Kilogram per cubic metre. The factor is 1,000, and the inverse is 0.001. The table below gives the same value in every density unit at once.

Method and background

How this is calculated

Density is mass over volume, held here against kilograms per cubic metre. Water at four degrees is almost exactly one gram per cubic centimetre, which is a thousand kilograms per cubic metre, and that coincidence is not accidental: the kilogram was originally defined as the mass of a litre of water.

result = value * factor_from / factor_to
