Therefore, the specific gravity (which is dimensionless) for a liquid has the same numerical value as its density in units of g/cm3. Since the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures. S g = p s /p h20. S g = Specific Gravity of the substance

For example, to calculate the specific gravity of iron (whose density is 7870 kg/m 3):. SG iron = (7870 kg/m 3)/(1000 kg/m 3) = 7.87. From the specific gravity formula, we can note something: If SG > 1, the material density is higher than water density, and the material sinks into the water.; If SG < 1, the material density is lower than water density, …

Specific gravity is the ratio of the density of a substance to the density of a reference substance, which is usually water for liquids and air for gases. When water is used, it is at its highest density, which is at 4 °C or 39.2 °F. When air is used, it is most often room temperature air, at 20 °C or 68 °F. Pressure is most often 1 atm.

For example, beryllium has a specific gravity (sg) of 1.84 (1840 kg/m³). As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/ft³ (pounds per cubic foot) and if we know that a sample of aluminum has a sg of 2.5 then we can calculate that its density is 2.5 x 62.4 = 156 lbs/ft³.
