16 Οκτ 2023 · Specific Gravity (SG) is a special case of relative density. It is defined as the ratio of the density of a given substance, to the density of water (H 2 O). Substances with a specific gravity greater than 1 are heavier than water, and those with a specific gravity of less than 1 are lighter than water.
Specific Gravity or relative gravity is a dimensionless quantity that is defined as the ratio of the density of a substance to the density of the water at a specified temperature and is expressed as \(\begin{array}{l}SG=\frac{\rho _{substance}}{\rho _{H_2O}}\end{array} \)

What is specific gravity? Specific gravity is the “heaviness” of a mineral. It is defined as a number that expresses the ratio between the weight of a mineral and the weight of an equal volume of water.
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 is a measure of the density of a substance compared to the density of a reference substance, typically water at 4 degrees Celsius. It is a dimensionless quantity, meaning it has no units.
Specific gravity is a measure of the density of a material. It is dimensionless, equal to the density of the material divided by the density of water. Since water's density is one gram per cubic centimeter (under standard conditions), specific gravity has the same value as density expressed in grams per cubic centimeter.
