How to Calculate Mass

Mass is a fundamental property of physical objects which is a quantitative measure of an object’s resistance to acceleration. It is a measure of the amount of matter that an object contains.

Unlike weight, which can vary depending on gravitational force, mass remains constant regardless of location. Mass is typically measured in kilograms (kg) in the International System of Units (SI).

You can calculate mass using a formula

Mass Formula

To calculate the mass of an object when you know its density and volume, you can use the formula:

m = ρ × V

m = mass (kg)
ρ = density (kg/m³)
V = volume (m³)

graphic showing the mass formula where mass is equal to the density times the volume.

For example, alculate the mass of a block of aluminum. If the density of aluminum is 2,700 kg/m (you can confirm this using our metal weight calculator) and you have a block with a volume of 0.1 m³, you can calculate the mass as follows:

m = 2,700 kg/m³ × 0.1 m³
m = 270 kg

So, in this example, the mass of the aluminum block is 270 kilograms.

You can also use our cubic feet calculator to find the volume to use with this formula if needed.
