Gram per Cubic Centimeter (g/cm³)
The gram per cubic centimetre (g/cm³, equal to g/mL) is a common laboratory density unit. Water is about 1 g/cm³, which makes the number equal to specific gravity to a good approximation.
Symbol: g/cm³ (ASCII: g/cm3)
Quantity: density (mass per unit volume) and mass concentration
SI relation: 1 g/cm³ = 1000 kg/m³ (exact)
Derivation: 1 g/cm³ = 10⁻³ kg ÷ 10⁻⁶ m³ = 1000 kg/m³
Exact: yes, by definition
Same quantity as kilogram per liter (kg/L) : the factor between them is exactly 1.
Typical uses
- Material and mineral densities
- Laboratory measurements of liquids and solids
- Polymer and resin datasheets
