To calculate the specific gravity (SG) of an object, you compare the object's density to the density of water: Because the density of water in g/cm 3 is 1.0, the SG of an object is will be almost the same as its density in g/cm 3. However, specific gravity is a unitless number, and is the same in the metric system or any other measurement system.
