How many ounces of beer are equivalent to 1 oz of alcohol?

To determine how many ounces of beer are equivalent to 1 ounce of alcohol, it's essential to understand that different types and brands of beer have varying alcohol by volume (ABV) percentages. Generally, the average beer has an ABV of around 5%. This means that there are approximately 0.6 ounces of pure alcohol in a typical 12-ounce beer.

To find out how many ounces of beer equate to 1 ounce of alcohol, you can use the following calculation: if there are about 0.6 ounces of alcohol in a 12-ounce beer, then to equal 1 ounce of alcohol, you will need more than 12 ounces of beer. Specifically, you would need around 16-17 ounces of beer, based on the equation:

1 oz alcohol = 12 oz beer / 0.6 oz alcohol = 20 oz beer.

Thus, the choice that reflects this calculation of needing approximately 20 ounces of beer to achieve 1 ounce of alcohol is the most accurate.
