WebApr 2, 2024 · Specific gravity is the ratio of the object's density to the density of water, i.e.: The units cancel out in the ratio. Therefore, the specific gravity is a unitless number. The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit.
