Density calculator
In physics, the density is denoted by the symbol ρ (read as ròu). The international main unit is kg/m3,
and the common unit is g/cm3. Its mathematical expression is \(ρ=m/V\). In the International System
of Units, the main unit of mass is kilograms, and the main unit of volume is cubic meters, so the mass
of 1 cubic meter of material is taken as the density of matter. For non-uniform substances, it is
called "average density".
Density calculation:
Density: \(d=m/v\)
d = density, m = mass, v = volume
