Difference Between Density and Specific Gravity

Sep 03, 2019· What Is Specific Gravity? Specific gravity is a measure of density relative to the density of a reference substance. The reference material could be anything, but the most common reference is pure water. If a material has a specific gravity less than 1, it will float on water.

Specific Gravity and Bulk Density | Mining | SGS

"Specific gravity" is the density of a material relative to water. Since rocks are comprised of several distinct mineral phases, they do not have a fixed specific gravity. Instead, a rock's "bulk density" arises as a result of the percentage of all minerals in a sample multiplied by the specific gravity of each.
