Shows the density of materials and liquids in science (g/cm³), engineering (kg/m³) and US (lb/ft³) units.

How to Use Density Converter

  1. 1
    Enter a valueDecimals and negative numbers (for temperature, say) are accepted.
  2. 2
    Choose unitsPick the unit you have and the unit you want. The swap button reverses the direction.
  3. 3
    Read, copy or shareResults show up to six decimal places. Copy them or create a share link with the same value.

Examples

Water, 1 g/cm³, in kg/m³
Input: 1 g/cm³ → kg/m³
Result: 1000
62.4 lb/ft³ in kg/m³
Input: 62.4 lb/ft³ → kg/m³
Result: 999.552115

Common Use Cases

  • Matching density units in material specs
  • Estimating liquid weight from volume
  • Converting lb/ft³ from US sources

Frequently Asked Questions (FAQ)

Are g/cm³ and g/mL the same?

Yes, because 1 mL = 1 cm³. kg/L has the same value too.

How is this different from specific gravity?

Specific gravity is a unitless ratio to water (about 1 g/cm³), so it is nearly the same number as g/cm³.
