Density of the cube: 1 kg/m3

Kilogram per cubic metre is an SI derived unit of density, defined by mass in kilograms divided by volume in cubic metres. The official SI symbolic abbreviation is kg·m−3, or equivalently kg/m3.[1]


1 kg/m3 is equivalent to:

= 0.001 g/cm3 (exactly)
≈ 0.06243 lb/ft3 (approximately)
≈ 0.1335 oz/gal (approximately)

1 g/cm3 = 1000 kg/m3 = 1,000,000 g/m3 (exactly)

1 lb/ft3 ≈ 16.02 kg/m3 (approximately)

1 oz/gal ≈ 7.489 kg/m3 (approximately)

Relation to other measures[edit]

The kilogram was originally based on the mass of one litre of water, thus the density of water is about 1000 kg/m3 or 1 g/cm3. In chemistry, g/cm3 is more commonly used.
