  • 3 Ways to Test the Specific Gravity of Liquids - wikiHow

    Apr 08, 2019 · Specific gravity, also referred to as relative density, is used to relate the weight or density of liquids to that of water. Specific gravity is a unitless measurement that is derived as a ratio of either the weight of another liquid or the density of another liquid divided by the weight or density of water.
