In the case of Sapphire Gin & Tonic, the number of degrees is 47 degrees.

The degree of alcohol indicates the volume percentage of ethanol contained in the wine, usually expressed as a volume ratio at 20°C. For example, a 50-degree wine indicates that in 100 ml of wine, there are 50 ml of ethanol (at 20°C), and the alcohol content is usually calculated by volume, so after the alcohol concentration, "Vol." is added to show the difference from the weight calculation.

The invention of the U.S.-made alcoholic beverages predates the emergence of the standard alcoholic beverages, and they are all expressed in terms of alcoholic purity "proof". However, it is possible to convert between the three degrees. Therefore, if you know the English measure and want to calculate its American measure or standard measure, you can do so with the following formula:

Standard measure x 1.75=English measure

Standard measure x 2=American measure

English measure x 8 ÷ 7=American measure

Extended information:

The degree of beer, on the other hand, does not indicate the amount of ethanol, but rather the concentration of the raw material used in the production of the beer, i.e., the wort, which, in the case of a 12-degree beer, is a concentration of leachate from the wort of 12% (w/w) before the fermentation of the wort. The leachate in the wort is a mixture of many ingredients, dominated by maltose.

The alcohol in beer is converted from maltose, from which it can be seen that the alcohol content is less than 12 degrees. Such as common light-colored beer, alcohol content of 3.3-3.8%; strong-colored beer alcohol content of 4-5%.
