Specific gravity
Description
A unitless measurement of relative density. Specific gravity is calculated as the ratio of the density of the material to the density of a standard. For liquids and solids, the standard is water. Since water has a density of 1.00 g cm-3, the numerical value of the specific gravity and density are equal.
