Why Calculate Specific Gravity?

The specific gravity calculator determines the relative density of a substance compared to cold freshwater; very useful for knowing if a material floats or sinks, or estimating the amount of alcohol in your homebrew beer.

Why is specific gravity important?

Significance and Use

4.1 Specific gravity is an important property of fluids being related to density and viscosity. Knowing the specific gravity will allow determination of a fluid's characteristics compared to a standard, usually water, at a specified temperature.

What is the point of specific gravity?

The specific gravity of a substance is characteristic; it is the same for different samples of a substance (if pure, the same in composition, and free from cavities or inclusions) and is used to help identify unknown substances.
