Calculate mass, volume, or density with metric and US units, plus convenient density presets for water, metals, concrete, gasoline, and wood.

Divide mass by density.

Mass to Volume Formula

The following equation is used to convert a mass into a volume.

V = m / D
  • Where V is the total volume
  • m is the total mass
  • D is the density (mass/volume)

To calculate volume from density, divide the mass by the density.

* Rounded to 3 decimals. Uses an illustrative density of 1 kg/L, not a temperature-corrected water measurement. At that density, 1 US gallon ≈8.3454 lb and 1 lb ≈0.11983 US gallon. Actual density varies with conditions.

Mass to Volume Definition

Converting mass into volume requires that you determine the density of the material and divide the mass by that density.
