Alcohol is sold with a number called "alcohol by volume" or ABV. In America, most beer is 3.4%ABV. To figure out the proof, simply double the ABV number. Vodka is generally 40%ABV, so in the United States it would be 80 proof. Other countries may have other standards that alter the proof number.
A bottle will usually state it's alcohol by volume (ABV) as "proof" . Proof is double what the percentage of alcohol is. So, a bottle of 60 proof spirits would be 30% alcohol by volume. The highest percentage alcohol in a spirit that I've seen is 151 proof, and that was a bottle of rum.
The "Proof" of an alcoholic beverage is an indicator of it's alcohol content on a 200 point scale. Take the Proof # and divide it by 2 to find out what the percentage is. So, to answer you specific question, 86/2= 43. Therefore 86 proof alcohol is 43 percent alcohol.
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
7:4 ratio. 70 proof is approx 40% 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
