the higher the proof the stronger - more alcohol - there is. In the UK 70 dgree proof was the standard strength of whiskey - 40% alcohol. 100 proof is 57.1% alcohol. 175 proof is 100% alcohol. In the USA it is different. 100 proof would be 50% alcohol, 70 proof would be 35% alcohol. 200proof would be 100% alcohol. ie double
'Proof' is a unit of measurement equal to 1 half of 1 percent. Therefore, 150 proof is 75% Alcohol by Volume (although at this point, you're more likely drinking moonshine or grain alcohol and not whiskey)
Alcohol proof is double the actual percentage of alcohol. 100 proof is 50% alcohol, 80 proof is 40%, and 65 proof is 32.5%
1 ounce = 28.3495 grams; 200 alcohol proof = 100% alcohol content. 2 ounces of 80 proof (40% alcohol) whiskey would be 56.699 grams of whiskey with 22.6796 grams of pure alcohol.
proof is double the alcohol percentage. 40% alcohol= 80 proof
80 proof means it has a 40% alcohol by volume.
Bacardi is 80 proof.
80 proof.
it is 80 proof which is 40 percent alcohol
They sell an 80 proof(40% alcohol) and a 100 proof(50% alcohol).
80 proof, 40% alcohol.
40% alcohol is 80 proof and about the average proof of many hard liquors.
100% pure alcohol is 200 proof. So 100 proof is 50% alcohol.
