Specific Gravity

specific gravity, ratio of the weight of a given volume of a substance to the weight of an equal volume of some reference substance, or, equivalently, the ratio of the masses of equal volumes of the two substances. Unlike density, which has units of mass per volume, specific gravity is a pure number, i.e., it has no associated unit of measure.

DETERMINATION OF ALCOHOL CONTENT USING SPECIFIC GRAVITY

From Wikipedia, the free encyclopedia. The point at which the surface of the liquid touches the stem of the hydrometer is noted. Hydrometers usually contain a paper scale inside the stem, so that the specific gravity can be read directly. The scales may be Plato, Oechsle, or Brix, depending on the purpose.

Specific gravity

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.
