How this calculator figures out the calories in alcohol

This calculater uses the following formula to figure out the calories in an alcoholic drink based on the amount and alcohol percentage using the following value.

1 US ounce = 29.5735 milliliters (ml)
1 ml of alcohol weighs .8 grams
1 gram of alcohol = 7 calories

Here's an example:

12 ounces of 5% beer = 12 x 29.5735 = 354.882 ml
354.882 x .05 = 14.19536 grams of alcohol
14.19536 * 7 = 99.36752 calories from alcohol
