Specific gravity | Formula, Units, & Equation | Britannica
WEBspecific gravity, ratio of the density of a substance to that of a standard substance. The usual standard of comparison for solids and liquids is water at 4 °C (39.2 °F), which has a density of 1.0 kg per litre (62.4 pounds per cubic foot).
Specific Gravity - Definition, Calculation, Solved Examples, FAQs
WEBSpecific gravity is a dimensionless quantity that is defined as the ratio of the density of a substance to the density of the water at a specified temperature. The density of water at 4 0C is commonly used as a reference point.
Relative density - Wikipedia
WEBRelative density, also called specific gravity, is a dimensionless quantity defined as 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 ...
Density vs. Specific Weight and Specific Gravity - The Engineering ToolBox
WEBSpecific Gravity (Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of water - at a specified temperature and can be expressed as. SG = ρ substance / ρ H2O (2)

Specific gravity (video) | Fluids | Khan Academy
WEBIn this video David explains what specific gravity means. He also shows how to calculate the value for specific gravity and use it to determine the percent of an object that will be submerged while floating.
Specific Gravity Definition and Values - ThoughtCo
WEBJan 15, 2020 · Specific gravity is the ratio of the density of a substance to the density of a reference substance, which is usually water for liquids and air for gases. When water is used, it is at its highest density, which is at 4 °C or 39.2 °F.
Specific Gravity - Definition of Specific Gravity - ThoughtCo
WEBJan 10, 2018 · The specific gravity of a substance is the ratio of its density to a specified reference substance. This ratio is a pure number, containing no units. If the specific gravity ratio for a given substance is less than 1, that means …
Specific gravity: what it is, formula, uses and examples
WEBJan 25, 2020 · Specific gravity, often abbreviated as GE or SG, is a measurement that compares the density of a substance to the density of water at a specific temperature and pressure. In other words, specific gravity tells us how much denser or less dense a material is compared to water. Definition of density.
What Is Specific Gravity? - METTLER TOLEDO
WEBSpecific gravity, also known as relative density, measures the density of a substance compared to the density of water. Specific gravity is related to density, as both are physical properties used to determine how "dense" a particular material is. This material can be a gas, liquid, or solid.
