ABV Calculator

5/5 - (1 vote)

If you want to calculate the alcohol content of your homebrew beer or your favourite whisky, the ABV calculator (alcohol by volume calculator) is the perfect gadget for you. It will help you estimate the percentage of alcohol in any liquor based on its initial and final specific gravity.

This unit is a standard measure of the quantum of alcohol (ethanol) contained in a given volume of a specific alcoholic beverage. It is expressed as a volume percentage. By theoretical definition, it is the number of millilitres (mL) of pure ethanol present in a 100 mL of solution at 20°C (68°F).

The ABV standard is used worldwide. The standard method of estimating ABV is to apply the specific gravity. It is the relative density of a liquid compared with that of water. When fermentation occurs, the specific gravity of the liquid changes.

You can monitor the continuous change to find the alcohol content of your drink. All formulas for finding the ABV give approximate values, as they are found empirically rather than derived. You can measure the ABV content of the alcohol content by weight also.
