About the Mass Calculator
Mass is the measure of the amount of matter in an object. It is a fundamental property of matter and one of the base quantities in the International System of Units (SI). This calculator determines mass based on an object's density and volume.
The Mass Formula
The relationship between mass (m), density (ρ), and volume (V) is given by the formula:
m = ρ * V
Mass vs. Weight
It's important not to confuse mass with weight. While they are related, they are not the same thing:
- Mass is an intrinsic property of an object and is the same everywhere (on Earth, on the Moon, in space). Its SI unit is the kilogram (kg).
- Weight is the force of gravity acting on an object's mass (Weight = mass × gravitational acceleration). It changes depending on the gravitational field. Its SI unit is the Newton (N).
Our calculator helps you find the mass of an object. If you need to find its weight, you can use our Weight Calculator.
