Density Converter
Convert density among kg/m³, g/cm³, g/mL, and lb/ft³ using kg/m³ as the reference.
How to use
- Enter density and choose its measured and desired notation among kg/m³, g/cm³, g/mL, and lb/ft³.
Capabilities and scope
Compare mass-per-volume density values across SI, laboratory, and customary notations.
How it works
kg/m³ is the reference; g/cm³ and g/mL each equal 1000 kg/m³ per unit, while lb/ft³≈16.0184634 kg/m³.
Example
1 g/cm³ = 1 g/mL = 1000 kg/m³.
Useful for
- Convert material density from g/cm³ to kg/m³
- Compare liquid g/mL with SI density
- Translate lb/ft³ datasets to SI
Before you use it
- Physical density can vary with temperature and pressure. The tool changes units only and does not correct measurement conditions.

Frequently asked questions
Why are g/cm³ and g/mL numerically equal?
Because 1 cm³ is exactly 1 mL, so the same mass gives the same density number.
