specific gravity

The ratio of the mass of a solid or liquid to the mass of an equal volume of distilled water at 4°C (39°F) or of a gas to an equal volume of air or hydrogen under prescribed conditions of temperature and pressure. Also called relative density.

specific gravity

(General Physics) the ratio of the density of a substance to that of water. See relative density

specif′ic grav′ity

the ratio of the density of any substance to the density of a standard substance, water being the standard for liquids and solids.
