### Convert Specific Gravity - Assaying, Microscopy

From an internet site on definition of specific gravity: Specific gravity is the density of a substance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density (but without any units).

More### Density to Specific Gravity Calculator

A conversion scale showing SG values for a range of density values will also be displayed, which will change according to the entered density.

More### Common Basic Formulas for Mineral Processing Calculations

As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity. A volumetric flask of one liter capacity provides the necessary accuracy.

More### How to Convert Density to a Specific Gravity Sciencing

May 20, 2018 Specific gravity is a ratio of the density of a substance to the density of a reference substance, usually water. Since the density of water is one gram per cubic centimeter, you calculate specific gravity by dividing the density of a substance by one gram per cubic centimeter.
