• Relative density - Wikipedia

    en.wikipedia.org/wiki/Specific_gravity Relative 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-gravity Specific 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.
  • Specific Gravity - Definition of Specific Gravity

    www.thoughtco.com/specific-gravity-2699007 Specific 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-gravity Specific 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.

  • Difference Between Density and Specific Gravity

    www.thoughtco.com/density-and-specific-gravity-differences-606114 Specific 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.
