What is the Alcohol Units Calculator?
A single beer, a glass of wine, and a shot of whiskey can carry surprisingly different amounts of pure alcohol. This calculator converts any drink into alcohol units so you can compare them honestly. One unit equals 10 milliliters of pure alcohol. The math is straightforward: multiply the drink's volume in milliliters by its ABV percentage, then divide by 1,000. A 12-ounce IPA at 6.5 percent ABV, for example, contains roughly 2.3 units — noticeably more than a 12-ounce light lager at 4.2 percent, which holds about 1.4 units.
Picture a backyard barbecue in Texas where the cooler is stocked with craft beer, wine, and hard seltzer. Three drinks in, you have had three servings but possibly five or six units. The calculator totals the units across the Number of Drinks field, estimates the calories (alcohol packs about 7 calories per gram, nearly as dense as fat), and gives a rough Hours to Sober estimate based on the body's average metabolism of one unit per hour.
Treat every result as an estimate, not a guarantee. Food, body size, medications, and tolerance all change how alcohol affects you. This is not medical advice, and it cannot tell you whether you are safe to drive — when in doubt, do not drive.
How to Use the Alcohol Units Calculator
- 1Type the serving size in the Volume (mL) box — a 12 oz can is about 355 mL, a 5 oz wine pour is about 148 mL.
- 2Enter the strength in the ABV % field, like 5 for a regular beer or 12 for a glass of red wine.
- 3Put how many of that drink you had in the Number of Drinks field, for example 3.
- 4Read your Alcohol Units result to see the pure-alcohol content of one serving.
- 5Check Total Units (all drinks) and Calories (approx) to see the full tally for the evening.
- 6Glance at Hours to Sober (est.) — a rough guide to how long your body needs to clear it.
