relative density

Show Summary Details

Quick Reference

The ratio of the density of a substance to the density of some reference substance. For liquids or solids it is the ratio of the density (usually at 20°C) to the density of water (at its maximum density). This quantity was formerly called specific gravity. Sometimes relative densities of gases are used; for example, relative to dry air, both gases being at s.t.p.
