Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.

It is simply the ratio of density of substance taken to the density of reference substance. R.D = Density of substance / Density of reference substance. Specific gravity = Density of subs. / Density of water. Water is reference in this case.

Relative density (or) specific density, is the ratio of the density of a substance to the density of a given reference material. If a substance's relative density is less than one then it is less dense than the reference; if greater than one then it is denser than the reference. If the relative density...

Relative density (or) specific density, is the ratio of the density of a substance to the density of a given reference material. If a substance's relative density is less than one then it is less dense than the reference; if greater than one then it is denser than the reference. If the relative density is exactly one then the densities are equal; that is, equal volumes of the two substances have the same mass. Relative Density = Density of the substance/ Density of air.

Relative density = (mass of the substance in air at 20 Deg C)/(mass of equal volume of water at 20 Deg C). It is used as a reference to compare densities of different materials when all these densities are available at different temperatures.
