Definition of specific gravity in US English:

specific gravity


  • The ratio of the density of a substance to the density of a standard, usually water for a liquid or solid, and air for a gas.

    • ‘He was another scientist who worked on the problem of specific gravities.’
    • ‘The lower specific gravity of this new material also reduces tyre weight and rolling inertia, thus further improving fuel efficiency.’
    • ‘Invest in a hydrometer, which measures the specific gravity of liquids, available at winemaking supply shops.’
    • ‘The common glycols are colorless liquids with specific gravities greater than that of water.’
    • ‘Urinalysis is performed to assess specific gravity and urinary glucose level.’
