1. What is a Standard Drink?

A standard drink is a measure of alcohol consumption representing a fixed amount of pure alcohol. In Australia, a standard drink contains 10 grams of pure alcohol, which helps people track their alcohol intake consistently across different types of alcoholic beverages.

2. How Does the Calculator Work?

The calculator uses the NSW Health standard drink formula:

Where:

• \( volume \) — Volume of drink in milliliters (mL)
• \( ABV \) — Alcohol by volume percentage (%)

Explanation: The formula calculates how many 10g units of pure alcohol are in a drink based on its size and alcohol concentration.

3. Importance of Standard Drink Calculation

Details: Understanding standard drinks helps people monitor their alcohol consumption, stay within recommended limits, and make informed decisions about drinking.

4. Using the Calculator

Tips: Enter the volume of your drink in mL and the alcohol percentage (ABV) as shown on the label. All values must be valid (volume > 0, ABV between 0-100).
