The **kilogram per cubic metre** (symbol: **kg·m ^{−3}**, or

**kg/m**) is an SI derived unit of density, defined by mass in kilograms divided by volume in cubic metres.

^{3}## Conversions

1 kg/m^{3} is equivalent to:

- = 0.001 g/cm
^{3}(exactly) - ≈ 0.06243 lb/ft
^{3}(approximately) - ≈ 0.1335 oz/gal
^{[clarification needed]}(approximately)

1 g/cm^{3} = 1000 kg/m^{3} = 1,000,000 g/m^{3} (exactly)

1 lb/ft^{3} ≈ 16.02 kg/m^{3} (approximately)

1 oz/gal^{[clarification needed]} ≈ 7.489 kg/m^{3} (approximately)

## Relation to other measures

The kilogram was originally based on the mass of one litre of water, thus the density of water is about 1000 kg/m^{3} or 1 g/cm^{3}. In chemistry, g/cm^{3} is more commonly used.
