Density Calculator

Calculate density, mass, or volume using the density formula and convert between units.

Result

Fill in the fields above, then press Calculate.

A density calculator finds density, mass, or volume from any two known values using the formula density = mass / volume.

Select what to solve for (density, mass, or volume), enter the known values with their units, and the calculator solves using d = m/v. Results are displayed in your chosen units.

Examples

Find density of an object

An object weighs 500 g and has a volume of 185 cm³. Density = 500 / 185 = 2.70 g/cm³ (similar to aluminum).

Find volume from mass and density

100 g of gold (density 19.3 g/cm³): Volume = 100 / 19.3 = 5.18 cm³.

Frequently Asked Questions

What is the densest common material?
Osmium is the densest naturally occurring element at 22.59 g/cm³. Gold (19.3 g/cm³) and lead (11.34 g/cm³) are commonly known dense materials.
What is the difference between density and specific gravity?
Specific gravity is the ratio of a substance's density to the density of water (1 g/cm³). So a material with density 2.7 g/cm³ has a specific gravity of 2.7 — it is dimensionless.

Quick Tips

  • •Water has a density of exactly 1.0 g/cm³ at 4 degrees C — use it as a reference point.
  • •Objects with density less than water float; those with density greater than water sink.
  • •Temperature affects density — most materials expand (lower density) when heated.
