specific 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 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.
15 Ιαν 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.
Relative density, also called specific gravity, [1] [2] 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.
10 Ιαν 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 the material will float in the reference substance.
21 Νοε 2023 · The specific gravity is the ratio between the density of an object, and a reference substance. The specific gravity can tell us, based on its value, if the object will sink...
Specific gravity, more formally known as relative density, is a measure of the density of a substance in comparison to the density of water. For solids and liquids, specific gravity is generally measured in relation to water at its densest state (at temperatures of 4 Celsius or 39.2 Fahrenheit), and for gases to room Temperature air.
