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). … 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. The density of … See more Relative density can be calculated directly by measuring the density of a sample and dividing it by the (known) density of the reference substance. The density of the sample is simply its mass divided by its volume. Although mass is easy to measure, the … See more • Fundamentals of Fluid Mechanics Wiley, B.R. Munson, D.F. Young & T.H.
