Cheapen Your Drinking Experience But Watch the Calories

 One alcohol unit is 10 milliliters (ml) which weighs 8 grams. One gram of pure alcohol has 7 calories.

Alcohol labels usually say "Proof" which is actually the percentage of alcohol multiplied by 2. So if something is 100 Proof, it's 50% alcohol. So 200 Proof is 100% alcohol, and so on. For a complete list of alcohol content, visit the Alcohol Content Database.

Let's say you have a beer with 10% alcohol (20 Proof) in a 12 fluid ounce can. What's 10% of 12? 

12 * 0.10 = 1.2 fluid ounce of alcohol per can. We need to convert this from fluid ounces to milliliters. 1.2 * 29.574 = 35.4882 milliliters of alcohol content. Now we must figure out grams. If 10 ml of alcohol weighs 8 grams, then 1 ml of alcohol weighs 0.8 grams.

Now we take 0.8 * 35.4882 to get the grams of our sample: 28.39056 grams of alcohol in a 12 fluid ounce can of beer with 10% alcohol.

For calories we take 7 calories * 28.39056 grams to get the calories: 198.73392 calories.
