The meaning of SPECIFIC GRAVITY 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.
1、specific weight = weight/volume就是比重，单位是 （N/m^3或者 lb/ft^3）而gravity 指的是地心引力,所以不是用力来算的,而是用密度,所以,specific gravity=density /density of water @4 摄氏度，可翻译为相对密度。2、,没有单位（无量纲）。
Related to specific gravity:Specific weight specific gravity n. The ratio of the mass of a solid or liquid to the mass of an equal volume of distilled water at 4°C (39°F) or of a gas to an equal volume of air or hydrogen under prescribed conditions of temperature and pressure. Also...
What is the specific gravity of water at 90 °C ? Situation: An engineer needs density for an experiment with a glider. Local temperature = 74.3°F = 296.7 K. Local pressure = 27.3 in.-Hg = 92.45 kPa. Find: (a) Calculate density using ...
Specific gravities, relative to an isotopically defined pure water at 4°C, have been determined on natural sea waters covering the salinity range 9–41% at temperatures of 0–25°C. A mathematical expression has been computed for the relationship between specific gravity, salinity and temperature...

Forsolidsandliquids, 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. Because it is a ratio, it is given without units. Specific gravity can be shortened to SG or Sp....

Learn about specific gravity, its relation to density, and how to convert one unit to the other. See which instruments are used to measure specific gravity.
The specific gravity and density are calculated byEqs. (2.1)and(2.2), respectively. (2.1)Specificgravity=a(a+w)−b whereais the mass of specimen in air;bis the mass of specimen and sinker (if used) in water;wis the mass of totally immersed sinker if used and partially immersed wire....
