How to Calculate the Specific Gravity of a Substance

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/m3 that ratio is easy to find For example the density of gold is 19 300 kg/m3 so its specific gravity is the []
