The gram per cubic centimetre is a unit of density in International System of Units (SI), and is commonly used in chemistry. Its official SI symbols are g/cm³, g·cm⁻³, or g cm⁻³. It is equal to the units gram per millilitre (g/mL) and kilogram per litre (kg/L). It is defined by dividing the gram, a unit of mass, by the cubic centimetre, a unit of volume. It is a coherent unit in the CGS system, but is not a coherent unit of the SI.

The density of water is approximately 1 g/cm³, since the gram was originally defined as the mass of one cubic centimetre of water at its maximum density at approximately 4 °C (39 °F).
