# Conversion of density units

The density (the volumetric mass density, specific mass) of a substance is its mass per unit volume. The symbol for density is ρ (Greek letter rho). Density is defined as mass divided by volume. The formula is ρ = m/V, where m = mass and V is volume. The basic SI density unit is kg/m
