EngineerHub.orgHow to use this calculator
Measure or obtain the mass and the volume of the same sample, enter both values, and read the density.

Background
Engineering basis, equations, assumptions, interpretation and practical limitations for this calculator.
Density = mass ÷ volume
Both measurements must refer to the same sample and condition.
- Use displacement for irregular solid objects.
- Remove trapped air when measuring liquids.
- For powders, decide whether loose or compacted bulk density is required.
Frequently Asked Questions
Practical questions about assumptions, inputs, interpretation and limitations.
Water is approximately 1000 kg/m³ near room temperature, but the precise value changes with temperature and pressure. Use a temperature-specific value when higher accuracy is required.
Density is mass divided by volume: ρ = m/V. Enter mass and volume in compatible units and the calculator converts them internally before reporting the result.
For a solid that is compatible with the liquid used, displacement in a graduated container can be used: the increase in liquid volume is the object's displaced volume.
Bulk materials contain void space. Particle arrangement, moisture, vibration and compaction change the amount of void space and therefore change bulk density.
No. Density has units of mass per volume. Specific gravity is a dimensionless ratio comparing a material's density with a reference density, commonly water for liquids and solids.
