how many mg in 1 unit of alcohol
Unit of alcohol One unit of alcohol (UK) is defined as 10 millilitres (8 grams) of pure alcohol.[2][3] Typical drinks (i.e., typical quantities or servings of common alcoholic beverages) may contain 1â€“3 units of alcohol.[3]
Alcoholic drink The concentration of alcohol in a beverage is usually stated as the percentage of alcohol by volumeÂ  (ABV, the number of milliliters (ml) of pure ethanol in 100 ml of beverage) or as proof. In the United States, proof is twice the percentage of alcohol by volume at 60 degrees Fahrenheit (e.g. 80 proof = 40% ABV). Degrees proof were formerly used in the United Kingdom, where 100 degrees proof was equivalent to 57.1% ABV. Historically, this was the most dilute spirit that would sustain the combustion of gunpowder.
