Understanding Alcohol Measurements

Because beverages vary wildly in their Alcohol by Volume (ABV) percentages, tracking the sheer number of "drinks" you consume is often highly inaccurate. A pint of strong IPA contains significantly more alcohol than a shot of standard vodka.

Standard Measurements

  • UK Units: 1 Unit equals exactly 10 milliliters (or 8 grams) of pure alcohol.
  • US Standard Drink: 1 Standard Drink equals exactly 14 grams (or 0.6 fluid ounces) of pure alcohol.

Frequently Asked Questions

How many calories are in alcohol?

Pure alcohol (ethanol) is incredibly dense calorically, containing 7 calories per gram. This is nearly as calorie-dense as pure fat (9 calories per gram) and significantly more dense than carbohydrates or protein (4 calories per gram). These are estimates and may not reflect actual values. Always verify important calculations independently.
