Specific Gravity - Definition of Specific Gravity

Jan 11, 2018 · The specific gravity of a substance is the ratio of its density to a specified reference substance. This ratio is a pure number, containing no units. If the specific gravity ratio for a given substance is less than 1, that means the material will float in the reference substance. When the specific gravity ratio for a given material is greater than 1, that means the material will sink in the reference Solids and Metals - Specific GravitiesThe Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:Reade Advanced Materials - Specific Gravity Table for specific gravity readings for common world coinsSpecific Gravity Table (Typical) for Metals, Minerals and Ceramics from READE.

This little tool is called the hydrometer, which measures the density of a liquid. Hydrometers look a lot like thermometers, except they don't have an internal liquid that rises and falls. Instead the hydrometer has a weight at the bottom that is calibrated to a specific level. This hydrometer then sinks or rises depending on the density of the liquid. Lighter liquids will make the hydrometer sink and heavier liquids See more on study specific gravity readings for common world coins

How to Use a Hydrometer to Measure Alcohol in Beer?

The alcohol by volume tells brewers how much alcohol is in their brews. There are multiple ABV calculators online that make this calculation easy.
