Mass density

Mass density gives the mass per unit volume of a material or body, with the differential form applying it at a point in a continuous medium. For a uniform sample it reduces to mass divided by volume.

\rho = \frac{\mathrm{d} m}{\mathrm{d} V}

What the symbols mean

mass density (kg/m^3)
mass (kg)
volume (m^3)
