Density Unit Conversion Calculator

What is density and how do we measure it?

Density is the measure of mass per unit of volume. For any given quantity of material (i.e. air, water, steel), density is calculated by dividing the mass of the material by the volume the material occupies (i.e. ρ = M/V), and is expressed in the units of the mathematical relationship (i.e. kg/m3, lb/ft3 etc.).
