Density Calculator

Mass from volume, or volume from mass, for 19 materials with typical densities — water, steel, gold, oak, ice and more. 'Typical' is printed on the page, because alloys and woods vary.

Example — Mass of 2 m³ of water2000 kg

How we got it — the example, step by step

  1. Mass = density × volume.
  2. = 1000 kg/m³ × 2 m³ = 2000 kg.

Check it backwards

2000 kg ÷ 2 m³ = 1000 kg/m³ — the density of water we started with.

Questions people also ask

Why do the material densities say 'typical'?
Because they genuinely vary: oak runs roughly 600–900 kg/m³ depending on species and dryness, and steels differ by alloy. The table uses the standard textbook mid-values and says so; for engineering, measure your actual material.
