Density Unit Conversion Calculator

Density, Specific Gravity Definition Density and specific gravity have very similar, but not quite identical definitions. Density is the mass of material per unit volume. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 o C. Because specific gravity is a ratio, it is a unitless quantity.
