WebMar 26, 2016 · 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 find. For example, the density of gold is 19,300 kg/m 3, so its specific gravity is the following: WebJun 3, 2015 · The specific gravity ( γg) of a gas mixture is the ratio of the density of the gas mixture to that of air. It is measured easily at the wellhead in the field and therefore is used as an indication of the composition of the gas. The specific gravity of gas is proportional to its molecular weight ( Mg) if it is measured at low pressures where ... bauhaus baumarkt bad neuenahr
