  • How to Calculate the Specific Gravity of a Substance dummies

    By Steven Holzner . In physics, a substance's specific gravity is the ratio of that substance's density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m 3, that ratio is easy to example, the density of gold is 19,300 kg/m 3, so its specific gravity .
