1. What Are Alcohol Units?

Alcohol units are a simple way to measure the 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 units formula:

Where:

• Volume — The amount of liquid in milliliters (ml)
• ABV — Alcohol By Volume percentage (%)
• 1000 — Conversion factor (1000ml = 1 liter)

Explanation: The formula calculates how much pure alcohol is in a drink by multiplying the volume by the alcohol percentage, then converting to standard units.

3. Importance of Tracking Alcohol Units

Details: Tracking alcohol units helps people stay within recommended limits for safe drinking, understand their alcohol consumption, and make informed choices about drinking.

4. Using the Calculator

Tips: Enter the drink volume in milliliters and the Alcohol By Volume percentage. Common ABV values: beer (4-6%), wine (12-14%), spirits (40%).

5. Frequently Asked Questions (FAQ)

Q1: What are the recommended alcohol limits?
A: Guidelines vary, but many recommend no more than 14 units per week for both men and women, spread over 3+ days.

Q2: How many units are in a pint of beer?
A: A pint (568ml) of 5% ABV beer contains about 2.8 units (568 × 5 ÷ 1000 = 2.84).

Q3: What's the difference between ABV and proof?
A: In the US, proof is twice the ABV (e.g., 40% ABV = 80 proof). In the UK, proof was calculated differently but is now rarely used.

Q4: Does glass size affect alcohol units?
A: Yes. A large glass of wine (250ml at 13%) has 3.25 units, while a small glass (125ml) has 1.6 units - same ABV but different volumes.

Q5: How accurate is this calculation?
A: It's mathematically precise for the given inputs, but actual alcohol absorption can vary based on food, metabolism, and other factors.
