Relative density - Wikipedia
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 … See more Relative density ($${\displaystyle RD}$$) or specific gravity ($${\displaystyle SG}$$) is a dimensionless quantity, as it is the ratio of either densities or weights The reference material can be indicated using subscripts: See more See Density for a table of the measured densities of water at various temperatures.
