Divide the proof number by 2 to get the percentage of alcohol, as in 90 proof is 45 percent alcohol.

Proof is a unit of percentage of alcohol. 200 proof is pure alcohol. The term originates from prooving the strengh of a distilled liqour. You mixed an equal volumn of the product with that amount of black gunpowder. If it would burn it prooved that it was at least 50% alcohol or 100 proof.

Proof is twice the percentage of alcohol (by volume) in the liquor.
So, 90-proof liquor is 45% alcohol.

Alcoholic proof is a measure of how much ethanol is in an alcoholic beverage, and is approximately twice the percentage of alcohol by volume (ABV, the unit that is commonly used at present).
