The kilogram per cubic metre (symbol: kg·m−3, or kg/m3) is the coherent SI derived unit of density, defined by mass in kilograms divided by volume in cubic metres.[1]

Conversions[]

  • 1 kg/m3 = 0.001 g/cm3 (exactly)[2]
  • 1 kg/m3 ≈ 0.06243 lb/ft3 (approximately)
  • 1 kg/m3 ≈ 0.1335 oz/US gal (approximately)
  • 1 kg/m3 ≈ 0.1604 oz/imp gal (approximately)


  • 1 g/cm3 = 1000 kg/m3 (exactly)
  • 1 lb/ft3 ≈ 16.02 kg/m3 (approximately)
  • 1 oz/(US gal) ≈ 7.489 kg/m3 (approximately)
  • 1 oz/(imp gal) ≈ 6.236 kg/m3 (approximately)

Relation to other measures[]

The density of water is about 1000 kg/m3 or 1 g/cm3, because the size of the gram was originally based on the mass of a cubic centimetre of water.

In chemistry, g/cm3 is more commonly used.
