Physics Density: Mass Divided by Volume
Density tells you how much mass is packed into a space. This calculator divides mass by volume for the standard value.
What is the Physics Density Calculator?
Enter mass in kilograms and volume in cubic metres. Density in kg/m^3 is mass divided by volume. All physics tools here use standard textbook formulas, labelled as such.
How to use it
- Enter the values in the labelled units.
- Click Calculate Density.
- Read the result and its formula.
Worked example
A mass of 10 kg in 2 m^3 has a density of 5 kg/m^3.
What density is 10 kg in 2 cubic metres?
5 kg per cubic metre, from 10 divided by 2.
Frequently asked questions
What units should I use?
Use the units on the labels (kg, m, s, N, J, W) so the formula's result comes out in standard units.
Is this exact?
The formula is standard textbook physics; real measurements carry their own errors, but the arithmetic is exact.
