Relative Density
Relative density, abbreviated as RD, is the density or ratio of any substance relative to another substance. It sometimes may be called just gravity or specific gravity. Traditionally, specific gravity is used to compare the density of a substance relative to air (SG=1) or water (also SG=1).
