➢Relative density of a substance is defined as the ratio of its density to the density of water at 4°C.

➢Relative density is ratio of density of substance to that of water i.e.

Relative density = Density of water/Density of substance.

➢Since relative density is the ratio of two similar quantities, it has no unit.
