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 {{cvt|4|C|F}}.{{Cite web |title=What Is a Gram in Chemistry? |url=https://www.thoughtco.com/definition-of-gram-604514#:~:text=A%20gram%20is%20a%20unit,which%20water%20has%20maximum%20density). |access-date=2024-11-10 |website=ThoughtCo |language=en}}
