May 27, 2020 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.

In physics, a substance’s specific gravity is the ratio of that substance’s density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m3, so its specific gravity is the []

Specific gravity is commonly used in industry as a simple means of obtaining information about the concentration of solutions of various materials, or of quality control for polymer materials: to evaluate physical changes, or determine the degree of uniformity between samples or lots.

Specific Gravity Formula. The following formula is used to calculate the specific gravity of a substance. SG = ρ / ρW . Where SG is specific gravity. (unitless) ρ is the density of your substance (kg/m^3) ρW is the density of water (kg/m^2) A few things need to be kept in mind in order to accurately calculate specific gravity.

Dec 13, 2016 Since specific gravity is relative to the weight of an object in air and its weight in water, it is a ratio and isn't expressed in units (such as kg/m³). For instance, the SG of Diamond = 3.52 (whereas the density of Diamond = 3.52 g/cm³). In gemology, specific gravity is, usually, determined through an apparatus based on Archimedes' Principle.

The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:

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 ...
