99 % minus whatever the de-natured solution is.
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 double the alcohol percentage. 40% alcohol= 80 proof
the proof is used to tell you how much alcohol is in it. 100 proof is about 50% alcohol so jsut divide the proof by 2 the higer the proof the more alcohol
50% alcohol Proof ÷ 2 = % alcohol
C. Proof of alcohol consumed. This is because standard drinks of beer, wine and spirits hall have the same amount of alcohol, which is 0.6 oz of pure alcohol.
Alcohol proof is double the actual percentage of alcohol. 100 proof is 50% alcohol, 80 proof is 40%, and 65 proof is 32.5%
'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 is measured in proof. 100% proof whiskey is 50% alcohol. Everclear is 95% alcohol.
100% pure alcohol is 200 proof. So 100 proof is 50% alcohol.
it is 80 proof which is 40 percent alcohol
100% pure alcohol is 200 proof. A liquid containing 10.5% alcohol would thus be 21 proof
48 proof means 24 % alcohol. Sounds like maybe a high alcohol wine or cough medicine.
