# What is the definition of specific gravity

What is Specific Gravity?

Specific gravity is a measure of the density of a substance compared to the density of water. It is expressed as a ratio of the density of the substance to the density of water. It is also known as relative density and is an important physical property of a substance.

Specific gravity is an important property of a substance because it can be used to identify a substance. It is also used to compare the density of different substances. The higher the specific gravity, the denser the substance.

Specific gravity is calculated by dividing the density of a substance by the density of water. The density of water is 1 gram per cubic centimeter (g/cm3). For example, if the density of a substance is 3 g/cm3, then the specific gravity of the substance is 3.

Specific gravity is also used to measure the concentration of a solution. For example, the specific gravity of a solution can be used to measure the amount of sugar or salt in the solution.
