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. The bid-ask spread is also known as the bid-offer spread and buy-sell. This sort of asset spread is influenced by a number of factors:
SUMMARY
The relative density of a substance is also known as specific gravity. The relative density of a substance can be defined as the ratio of the density of the given substance to the density of the standard substance. Relative density is the ratio of the mass of a substance to that of a reference substance...
Relative density, or specific gravity,[1][2] 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).
If a substance's relative density is less than one then it is less dense than the reference; if greater than 1 then it is denser than the reference. If the relative density is exactly 1 then the densities are equal; that is, equal volumes of the two substances have the same mass.......
