WebJan 27, 2015 · specific gravity noun : the ratio of the density of a substance to the density of some substance (as pure water) taken as a standard when both densities are obtained by weighing in air More from Merriam-Webster on specific gravity Britannica.com: … Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" (often abbreviated r.d. or RD) is often preferr…
