How to use the Density Calculator

The Density Calculator works out your density (mass ÷ volume) in an instant. Enter mass and volume and the result updates as you type — it is free, needs no sign-up, and runs entirely in your browser so your figures stay private.

  1. Enter the mass.
  2. Enter the volume.
  3. Read off your density (mass ÷ volume) — the calculator updates automatically, with no button to press.

Formula

The Density Calculator uses the formula:

Density (mass ÷ volume) = Mass ÷ Volume

Worked example

For example, with mass of 100 and volume of 50, the density (mass ÷ volume) is 2.0000.

Inputs used
Mass 100
Volume 50
Results
Density (mass ÷ volume) 2.0000

Key terms explained

Density
Mass per unit volume, calculated as mass ÷ volume.
Volume
The amount of three-dimensional space an object occupies, measured in cubic units.

Frequently asked questions

Divide mass by volume: ρ = m ÷ V. A 100 g object occupying 50 cm³ has a density of 2 g/cm³.

Use any consistent pair, such as grams and cubic centimetres (g/cm³) or kilograms and cubic metres (kg/m³). The result follows your units.

Water is about 1 g/cm³, or 1000 kg/m³. Materials denser than water sink, while less dense ones float.

Yes. Mass equals density × volume and volume equals mass ÷ density. This tool divides mass by volume to give density.
