# Gram per cubic centimetre

**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/cm^{3}, 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/cm^{3} or 1000 kg/m^{3}, since the gram was originally defined as the mass of one cubic centimetre of water at its maximum density at 4 °C.

## Conversions

1 g/cm^{3} is equivalent to:

- = 1000 g/l (exactly)
- = 1000 kg/m
^{3}(exactly) - ≈ 62.42796 lb/ft
^{3}(approximately) - ≈ 133.52647 oz/gal (approximately)

1 kg/m^{3} = 0.001 g/cm^{3}(exactly)

1 lb/ft^{3} ≈ 0.01602 g/cm^{3} (approximately)

1 oz/gal ≈ 0.00749 g/cm^{3} (approximately)
