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/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.
