Ethanol energy
Ethanol = 0.789 g/ml × 7 kcal/g
14 g × 7 = 98 kcal
A weekly total of 1,056 calories is about 0.3 lb of fat if not offset.
Ethanol supplies 7 calories per gram, second only to fat, so alcohol adds up fast. A standard beer holds about 150 calories; a 5-oz wine about 125.
Enter a drink's strength and size for calories per drink and a weekly total.
How to calculate alcohol calories
To calculate alcohol calories, multiply the ethanol grams by 7 and add any residual carbohydrate. Beer and cocktails carry extra sugar beyond the alcohol.
Worked example: a 12 oz beer at 5% ABV holds about 14 g of ethanol, near 98 calories from alcohol plus carbs.
