Gram per cubic centimetre is a unit of density in the CGS system, commonly used in chemistry, defined as mass in grams divided by volume in cubic centimetres. The official SI symbols are g/cm3, g·cm−3, or g cm−3. It is equivalent to the units gram per millilitre (g/mL) and kilogram per litre (kg/L). The density of water is about 1 g/cm3 or 1000 kg/m3, since the gram was originally defined as the mass of one cubic centimetre of water at its maximum density at 4 °C.

1 g/cm3 is equivalent to:
1 kg/m3 = 0.001 g/cm3(exactly)
1 lb/ft3 ≈ 0.01602 g/cm3 (approximately)
1 oz/gal ≈ 0.00749 g/cm3 (approximately)
