What is the Density Calculator?
Calculate density from mass and volume, or check a material against water.
Enter mass and volume and the Density Calculator returns density, in kilograms per cubic metre and in water it will. Results update as you type, and nothing you enter leaves your device.
How it is calculated
ρ = m ÷ V
How to use it
- Enter mass in g.
- Enter volume in cm³.
- Read density in the results panel. It updates as you type.
- Change any value to compare scenarios, or use Share to send the result as a link.
