Difference Between Density and Specific Gravity
Both density and specific gravity describe mass and may be used to compare different substances. They are not, however, identical measures. Specific gravity is an expression of density in relation to the density of a standard or reference (usually water).

Specific Gravity Meters  McMasterCarr
Concentration meters with automatic temperature compensation standardize readings at 68° F to prevent inaccurate results in fluctuating temperatures. Concentration meters with freezingpoint scale measure the freezing point of propylene glycol and ethylene glycol as well as the specific gravities of battery acids from 1. 15 to 1.30.

Specific gravity  Wikipedia
Specific gravity, also called relative density, is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance.

A water jacket and connecting holes are used to inject water and elutriate a bed of material in each. Some companies have produced this type of enhanced gravity separator, the Knelson being the best known. Concentration by a MacNicol is different because it uses a fluidized bed (eluition) into which heavier minerals sink.

Gravity Separation  ScienceDirect
To determine the suitability of gravity separation processes to a particular ore type, a concentration criterion is commonly used. A concentration criterion (CC) can be defined as (16.1) Concentration Criterion = SG of heavy mineral − SG of fluid SG of light mineral − SG of fluid where SG = specific gravity (or density), and the fluid is ...

API gravity  Wikipedia
The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.. API gravity is thus an inverse measure of a petroleum liquid's density relative to that of water (also known as specific gravity).
