SG = Specific gravity (e.g. pure water = 1) Density of Substance (ρ) This is the measure of the amount of mass per unit volume of a substance. The density is derived by dividing the mass of a quantity of substance by its volume. Specific Gravity of Substance (SG) This is the ratio of the density of a substance compared to the density of pure water.

The name of the force that determines whether an object will sink or float on water is known as specific gravity. The formula for specific gravity establishes that if the specific gravity of a solid object or a liquid is greater than one, then the object or liquid in question will sink. If, however, the specific gravity is less than one, then the object or liquid in question will float.

Apr 08, 2019 · To test the specific gravity of liquids, first pour a sample of liquid into a container. You'll need to use a container that is deep enough to allow a hydrometer to float. Next, make sure the liquid is the same temperature that the hydrometer is calibrated to, or you will get an incorrect reading.
Specific gravity. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. The reference substance for liquids is nearly always water at its densest (at 4 °C or 39.2 °F); for gases it is air at room temperature (20 °C or 68 °F).
Apr 30, 2018 · To calculate specific gravity, you divide the density of the substance by the density of water at 4 degrees Celsius, since water achieves its maximum density at this temperature. In CGS (centimeter, gram, second) metric units, the density of water is essentially 1 .
