Standard Drink Calculator

How to Use the Calculator

Beer, wine, or distilled spirits – you only need 2 pieces of information to calculate how many standard drinks are in a container:

1) Volume (typically shown as ounces or mL)
2) Alcohol by volume (typically shown as % ABV or ‘proof’)

This works for canned cocktails and other ready-to-drink (RTD) beverages too, regardless of whether they are spirit-, wine-, or malt-based.

The Dietary Guidelines for Americans defines moderate alcohol consumption as up to 2 drinks per day for males and up to 1 drink per day for females.

Enter the information below to calculate the number of standard drinks.
