Density Calculator

Calculate density, mass or volume from known values. Enter any two values and the calculator will determine the missing quantity.

Choose which quantity you want to calculate.

Density relationship

Density describes how much mass is contained in a given volume. The calculator converts compatible units before solving.

Density Formula

Density, mass and volume are directly related. If any two are known, the third can be calculated.

Rearranging the relationship gives mass = density × volume and volume = mass ÷ density.

How to Use the Density Calculator

1

Choose What to Calculate

Select density, mass or volume.

2

Enter the Known Values

Enter the two quantities you already know and select their units.

3

Click the calculate button to find the missing quantity.

4

Review Converted Values

Review the compatible mass, density and volume values used in the calculation.

Example Density Calculation

Find the density of a substance with a mass of 1,000 g and volume of 1,000 cm³.

  • Mass = 1,000 g
  • Volume = 1,000 cm³
  • Density = 1 g/cm³

Density = Mass ÷ Volume

1,000 ÷ 1,000 = 1 g/cm³.

Understanding Density

Density

Density is the amount of mass contained in a unit of volume.

Mass

Mass measures the amount of matter in an object.

Volume

Volume measures the three-dimensional space occupied by an object or substance.

Unit Conversion

The calculator converts selected units into a compatible system before calculating.

Frequently Asked Questions

Density is the mass of a substance divided by its volume. It indicates how concentrated the mass is within a given amount of space.
Density is calculated as mass divided by volume. The relationship can be rearranged to calculate mass or volume.
Common mass, volume and density units are supported, including g, kg, mg, lb, cm³, mL, L, m³, ft³, g/cm³, kg/m³, g/mL and lb/ft³.
Yes. Choose Mass or Volume from the Calculate menu and enter the other two known quantities.
For a homogeneous material under the same conditions, density generally does not change simply because the sample size changes.
