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.
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, air at room temperature (20 °C or 68 °F) is the reference. The term "relative density" is often preferred in ...
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.
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.
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.
www.khanacademy.org/science/physics/fluids/.../specific-gravity[MUSIC PLAYING THROUGHOUT] What does "specific gravity" mean? The specific gravity of an object is the density of that object divided by the density of water. The density of water is 1,000 kilograms per meter cubed. For instance, the density of gold is 19,300 kilograms per meter cubed. So the specific gravity of gold is 19.3. The density of ...
medlineplus.gov/ency/article/003587.htmUrine specific gravity is a laboratory test that shows the concentration of all chemical particles in the urine. After you provide a urine sample, it is tested right away. The health care provider uses a dipstick made with a color-sensitive pad. The color the dipstick changes to will tell the provider the specific gravity of your urine.
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  SG = Specific Gravity of the substance. ρ substance = density of the fluid or substance [kg/m 3]
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-606114Both density and specific gravity describe mass and may be used to compare different substances. They are not, however, identical measures. Specific gravity is an expression of density in relation to the density of a standard or reference (usually water).
