en.wikipedia.org/wiki/Specific_gravityRelative density, or specific gravity, is 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 at room temperature (20 °C or 68 °F). The term "relative density" is often preferred in ...
www.britannica.com/science/specific-gravitySpecific gravity, ratio of the density of a substance to that of a standard substance. Solids and liquids are often compared with water at 4 C, which has a density of 1.0 kg per liter. Gases are often compared with dry air, having a density of 1.29 grams per liter (1.29 ounces per cubic foot) under standard conditions.
www.thoughtco.com/specific-gravity-2699007Specific gravity is a concept that shows up in a variety of industrial applications, particularly as it relates to fluid dynamics. For example, if you've ever taken your car in for service and the mechanic showed you how small plastic balls floated in your transmission fluid, you've seen specific gravity in action.
www.omnicalculator.com/physics/specific-gravitySpecific gravity definition and the specific gravity equation. Specific gravity (also referred to as relative density) is the ratio of the density of a material compared to the density of water at 4 °C (39.2 °F). People usually choose that temperature as it is when water is at its densest.
www.merriam-webster.com/dictionary/specific%20gravitySpecific gravity definition is - the ratio of the density of a substance to the density of some substance (such as pure water) taken as a standard when both densities are obtained by weighing in air. How to use specific gravity in a sentence.
study.com/.../what-is-specific-gravity-definition-formula-calculation-example...The specific gravity of an object is the ratio between the density of an object to a reference liquid. Usually, our reference liquid is water, which has a density of 1 g/mL or 1 g/cm^3. Because ...
www.engineeringtoolbox.com/density-specific-weight-gravity-d_290.htmlSpecific 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  where SG = Specific Gravity of the substance
www.healthline.com/health/urine-specific-gravityA urine specific gravity test is a painless and easy test to take. Preparation is simple, and it only requires excluding a few things from your diet and temporarily stopping certain medications.
www.thoughtco.com/density-and-specific-gravity-differences-606114Specific gravity is an expression of density in relation to the density of a standard or reference (usually water). Also, density is expressed in units (weight relative to size) while specific gravity is a pure number or dimensionless.
www.medicalnewstoday.com/articles/322125A urine specific gravity test shows the density of urine compared with water. It can help doctors diagnose a variety of conditions, including dehydration, kidney problems, and a rare type of diabetes.
