Relative density

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 392 °F); for gases, air at room temperature (20 °C or 68 °F) is the reference The term "relative density" is often preferred in ....
