Alcohol Unit Calculator: Track Your Drinking Accurately

Instantly calculate the alcohol units in your drinks to better understand your consumption and stay within recommended health guidelines. Use our presets for common drinks or enter your own manually for a precise count.

Why Is Tracking Alcohol Units Important?

Understanding your alcohol intake is the first step toward responsible drinking and better health. Many people are unaware of how many units are in their favorite drinks, which can lead to unknowingly consuming more than the recommended limits. Our Alcohol Unit Calculator is a simple, effective tool designed to give you clarity and help you make informed decisions about your drinking habits. By knowing your intake, you can reduce health risks, manage your wellness, and maintain a balanced lifestyle.

How Are Alcohol Units Calculated?

An alcohol unit is a standard measure used to quantify the amount of pure alcohol in a drink. One unit is equivalent to 10ml or 8g of pure alcohol, which is the amount an average adult can process in about an hour. The number of units depends on both the size and the strength of the drink. The formula is:

(Strength (ABV %) × Volume (ml)) ÷ 1000 = Total Units


Understanding Units in Common Drinks

The number of units can vary significantly even in similar types of drinks. Here’s a quick guide:

  • Wine: A standard medium (175ml) glass of 13% ABV wine contains about 2.3 units. A large (250ml) glass has around 3.3 units.
  • Beer & Cider: A pint (568ml) of 4% ABV beer or cider has 2.3 units. For stronger beers, like a 5.5% ABV craft ale, a single pint can contain over 3 units.
  • Spirits: A single 25ml shot of 40% ABV spirits (like gin, rum, or vodka) contains exactly 1 unit.

Use our calculator on the right to get a precise number for any drink you have.

Frequently Asked Questions (FAQ)

ABV stands for "Alcohol By Volume." It is a percentage measure of the amount of pure alcohol in a given volume of a beverage. The higher the ABV, the stronger the drink and the more units it will contain.

A standard 750ml bottle of wine with a 13.5% ABV contains just over **10 units**. This is a significant portion of the recommended weekly limit of 14 units.
