What is difference between density and specific gravity? Density is defined as mass per unit volume. It has the SI unit kg m-3 or kg/m 3 and is an absolute quantity. Specific gravity is the ratio of a material's density with that of water at 4 C (where it is most dense and is taken to have the value 999.974 kg m-3).It is therefore a relative quantity with no units.
