1. What Are Alcohol Units?

An alcohol unit is a measure of the pure alcohol content in a drink. One unit equals 8 grams (10 milliliters) of pure alcohol in the UK, though this varies by country. The calculator helps determine how many standard units are within a given alcohol limit.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Limit} \) — Total alcohol limit in grams
• \( \text{Unit Size} \) — Grams of alcohol per standard unit

Explanation: The calculation divides your total alcohol limit by the size of one alcohol unit to determine how many units you can consume within that limit.

3. Importance of Alcohol Unit Calculation

Details: Understanding alcohol units helps with responsible drinking, staying within recommended limits, and comparing different alcoholic beverages.

4. Using the Calculator

Tips: Enter your total alcohol limit in grams and the standard unit size for your country (default is 8g for UK). All values must be positive numbers.

Q2: How do I convert drinks to grams of alcohol?
A: Multiply drink volume (ml) by ABV (%) and by 0.789 (density of ethanol).

Q3: What are recommended weekly limits?
A: Varies by country - typically 14 UK units (112g) for women and 14-21 UK units (112-168g) for men.

Q4: Does this account for different drink types?
