Density Units Information

Kilogram per cubic meter (kg/m³)

SI unit of density. One kilogram per cubic meter is the density of a substance with a mass of one kilogram occupying a volume of one cubic meter.

1 kg/m³ = 1 kg / 1 m³

Gram per cubic centimeter (g/cm³)

CGS unit of density. Commonly used in chemistry and materials science. Equal to 1000 kg/m³.

1 g/cm³ = 1000 kg/m³

Gram per milliliter (g/mL)

Common unit in chemistry. Equal to g/cm³ since 1 mL = 1 cm³. Often used for liquids.

1 g/mL = 1 g/cm³ = 1000 kg/m³

Kilogram per liter (kg/L)

Metric unit commonly used for liquids. Equal to g/cm³ since 1 L = 1000 cm³.

1 kg/L = 1 g/cm³ = 1000 kg/m³

Pound per cubic foot (lb/ft³)

Imperial unit of density. Commonly used in US engineering and construction.

1 lb/ft³ = 16.0185 kg/m³

Pound per cubic inch (lb/in³)

Imperial unit of density. Used for dense materials in engineering applications.

1 lb/in³ = 27679.9 kg/m³

Ounce per gallon US (oz/gal)

US customary unit for liquid density. Commonly used in US for liquid concentrations.

1 oz/gal (US) = 7.48915 kg/m³

Ounce per gallon UK (oz/gal)

Imperial unit for liquid density. Used in UK and Commonwealth countries.

1 oz/gal (UK) = 6.23602 kg/m³

Temperature

Density changes with temperature. Always note the temperature

Water Reference

Water at 4°C has density of 1000 kg/m³. Use as reference point

Understanding Density

Density is a fundamental physical property that describes how much mass is contained in a given volume. It's calculated as density = mass ÷ volume and is expressed in various units depending on the system of measurement and application.

Common Density Units

The most commonly used density units include:

kg/m³: SI unit, standard in scientific and engineering applications
g/cm³: CGS unit, commonly used in chemistry and materials science
g/mL: Equivalent to g/cm³, commonly used for liquids
lb/ft³: Imperial unit, common in US engineering and construction
lb/in³: Imperial unit for dense materials

Conversion Formulas

Key conversion factors between density units:

1 g/cm³ = 1000 kg/m³ (exact conversion)
1 g/mL = 1 g/cm³ = 1000 kg/m³ (equivalent units)
