1. What Are Alcohol Units?

Alcohol units are a standard way to quantify the actual amount of pure alcohol in a drink. One unit equals 10ml or 8g of pure alcohol, which is roughly what an average adult can process in one hour.

2. How the Calculator Works

The calculator uses the standard alcohol unit formula:

\[ Units = \frac{volume_{ml} \times ABV}{1000} \]

Where:

Explanation: The formula multiplies the drink volume by its alcohol percentage, then divides by 1000 to convert to standard units.

3. Importance of Unit Calculation

Details: Tracking alcohol units helps people stay within recommended limits for safer drinking and better health outcomes.

4. Using the Calculator

Tips: Enter the drink volume in milliliters and the ABV percentage (found on drink labels). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the recommended weekly alcohol limits?
A: Typically 14 units per week for both men and women, spread over 3+ days with alcohol-free days.

Q2: How many units are in common drinks?
A: A pint (568ml) of 5% beer = 2.8 units; 175ml glass of 12% wine = 2.1 units; 25ml shot of 40% spirit = 1 unit.

Q3: Why calculate units instead of counting drinks?
A: Drink sizes and strengths vary widely. Units provide a consistent measurement of actual alcohol consumed.

Q4: How long does alcohol stay in your system?
A: The liver processes about 1 unit per hour. Many factors affect this rate including weight, gender and food intake.

Q5: Are there health risks from regular drinking?
A: Regular consumption above recommended limits increases risks for liver disease, cancer, heart problems and mental health issues.
