Specific Gravity (Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of water - at a specified temperature

The density of water at 4 degree C is 1 kg/l and is the value usually used to calculate SG

 Density of Liquid kg/l then the SG is
