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[edit]
1 kg/m3 is equivalent to:
- = 0.001 g/cm3 (exactly)
- ≈ 0.06243 lb/ft3 (approximately)
- ≈ 0.1335 oz/gal[clarification needed] (approximately)
1 g/cm3 = 1000 kg/m3 = 1,000,000 g/m3 (exactly)
1 lb/ft3 ≈ 16.02 kg/m3 (approximately)
1 oz/gal[clarification needed] ≈ 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.
