Jan 25, 2020 · Specific gravity, often abbreviated as GE or SG, is a measurement that compares the density of a substance to the density of water at a specific temperature and pressure. In other words, specific gravity tells us how much denser or less dense a material is compared to water.
Definition: The ratio of the density of a solid or a liquid to that of water at 4°C is called the specific gravity of that substance. Alternatively, the specific gravity of a solid or a liquid is defined as the ratio between the mass of a certain volume of the substance to the mass of an equal volume of water at 4°C.
