About the Density Chemistry calculator

Find the density, mass or volume of a substance from the other two values, with mass entered in several units.

How to use the Density Chemistry calculator

  1. Choose what to solve for under Solve For.
  2. Enter the Mass (choose g, kg, mg or lb) and Volume (cm³), or the density.
  3. Press Calculate.

Formula and method

ρ = m ÷ V, so m = ρ × V and V = m ÷ ρ.

Worked example

27 g of aluminium occupying 10 cm³ has a density of 2.7 g/cm³.

Tips

  • Water has a density of about 1 g/cm³, so substances with a lower density float on it.
  • Density changes with temperature.

Frequently asked questions

How do I convert g/cm³ to kg/m³?
Multiply by 1,000. Water is 1 g/cm³ = 1,000 kg/m³.
