Density (volumetric mass density or specific mass) is the ratio of a substance's mass to its volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D (or d) can also be used: ρ = m V , {\displaystyle \rho ={\frac {m}{V}},} where ρ is the density, m is the mass, and V is the volume.
