How to Use Alcohol Content Calculator
The Alcohol Content Calculator turns ‘volume and ABV’ into pure alcohol grams and standard drinks. Pick a preset or enter custom values.
- Pick a preset — Beer, wine, spirit shot, cocktail, or custom.
- Enter volume and ABV — Volume in ml, ABV in %.
- Read the breakdown — The Alcohol Content Calculator shows pure alcohol grams, pure alcohol ml, US standard drinks, and proof.
Formula & Theory — Alcohol Content Calculator
The Alcohol Content Calculator uses three equations:
pure_ml = volume_ml × abv_percent ÷ 100
pure_g = pure_ml × 0.789
std_drinks = pure_g ÷ 14
proof_us = abv_percent × 2| Beverage | Volume | ABV | Pure alcohol | Standard drinks |
|---|---|---|---|---|
| Beer | 355 ml | 5% | 14 g | 1.0 |
| Wine | 150 ml | 12% | 14 g | 1.0 |
| Spirit (shot) | 44 ml | 40% | 14 g | 1.0 |
| Strong cocktail | 240 ml | 14% | 27 g | 1.9 |
Assumptions and Limits
The Alcohol Content Calculator uses 0.789 g/ml ethanol density and the US 14 g standard drink. The UK uses an 8 g unit; Australia uses 10 g. Convert by dividing pure grams by your local definition.
Use Cases for Alcohol Content Calculator
The Alcohol Content Calculator is useful for:
- Responsible drinking — Track standard drinks per session.
- Home bartending — Compare two recipes by total alcohol grams.
- Health log — Convert a varied night out into grams of ethanol.
- Labeling craft drinks — Quickly compute proof and standard drinks for menus.
The Alcohol Content Calculator removes the maths so you can focus on the drink — and the limit.
