Specific Gravity

The density of a substance is defined as  mass per unit volume.  The density of a substance is a characteristic property and has a definite value at a given temperature and pressure.  The density of one substance in relation to the density of another material (e.g. water) is known as specific gravity.  Therefore, specific gravity is the weight of a given substance referred to the weight of an equal volume of water at a definite temperature.
