The Alcohol Units & Drink Cost / Calories Calculator helps you find out how many units or standard drinks are in your beer, wine, or spirits — and how many calories from alcohol you consume per session, week, or month.
Instantly convert ABV% and serving size into UK units or US standard drinks, and estimate your total alcohol intake. Use it to check units in a pint of beer, units in a bottle of wine, or calories in mixed drinks.
The calculator supports both UK guidelines (1 unit = 10 ml pure alcohol) and US standard drinks (≈14 g ethanol). It’s a simple way to monitor your drinking habits, alcohol calories, and weekly consumption limits.
FAQ
- How many units are in a pint of beer?
A standard 568 ml pint of 5% beer equals about 2.8 UK units or 1.6 US standard drinks. - How many units are in a bottle of wine?
A 750 ml bottle of 12% wine contains roughly 9 UK units or 5 US drinks. - How many calories are in alcohol?
Pure alcohol provides around 7 kcal per gram — about 200–250 calories per pint of beer or 120 calories per glass of wine. - What’s the difference between UK units and US standard drinks?
UK unit = 10 ml of pure alcohol. US standard drink = 14 g of alcohol (≈ 17.7 ml). Results differ slightly but measure the same total alcohol content. - How many drinks per week is safe?
UK guidelines advise staying below 14 units per week. That’s about 6 pints of beer or 10 small glasses of wine. US guidelines recommend up to 1 drink per day for women and 2 for men. - How can I track my alcohol intake?
Use this calculator to total your weekly alcohol units, calories, and spending. It helps visualize how small changes (like lower-ABV options) reduce both intake and cost. - Does beer or wine have more units?
Wine is stronger per ml, but beer servings are larger. A pint of 5% beer ≈ 2.8 units, while a 175 ml glass of 12% wine ≈ 2.1 units. - How can I reduce alcohol calories?
Choose lower-ABV beers, smaller pours, or alcohol-free alternatives to lower total units and calories without cutting social habits.
