specific gravity, ratio of the density of a substance to that of a standard substance. The usual standard of comparison for solids and liquids is water at 4 °C (39.2 °F), which has a density of 1.0 kg per litre (62.4 pounds per cubic foot).

Specific Gravity (Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of water - at a specified temperature and can be expressed as SG = ρ substance / ρ H2O (2)
Relative density, also called specific gravity, is a dimensionless quantity defined as the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air ...
5 days ago · Learn how to calculate specific gravity, a unitless ratio of density of a substance to water, and use the calculator to find the specific gravity of different materials. See examples, FAQs, and compare specific gravity vs. density.
Specific gravity is the ratio of the object's density to the density of water, i.e.: Specific gravity = Density of an object Density of water Specific gravity = Density of an object Density of water. The units cancel out in the ratio. Therefore, the specific gravity is a unitless number.
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.
