Working

  1. 1ρ = 2700 ÷ 1000 = 2.7 g/cm³

Quick answer

Density equals mass divided by volume; water is 1 g/cm³ or 1,000 kg/m³.

ρ = m ÷ V

How to use the Density Calculator

  1. 1Enter mass in grams.
  2. 2Enter volume in cubic centimetres.
  3. 3Read density in several common units.

Frequently asked questions

What is the density of aluminium?

2.70 g/cm³ — about a third of steel, which is why it dominates aerospace and drinks cans.

Is specific gravity the same as density?

It is density relative to water, so numerically identical in g/cm³ but dimensionless.
