1. What is a Standard Drink?

A standard drink is a measure of alcohol consumption representing a fixed amount of pure alcohol. In the United States, one standard drink contains about 0.6 fluid ounces (14 grams) of pure alcohol.

2. How Does the Calculator Work?

The calculator uses the standard drink formula:

Where:

• \( Volume \) — Amount of beverage in fluid ounces (oz)
• \( ABV \) — Alcohol by volume percentage (%)
• 0.6 — Ounces of pure alcohol in one standard drink

Explanation: The formula calculates how many standard drinks are in a beverage based on its size and alcohol concentration.

3. Importance of Standard Drink Calculation

Details: Knowing standard drinks helps track alcohol consumption, understand health risks, and follow drinking guidelines for safe consumption.

4. Using the Calculator

Tips: Enter the beverage volume in ounces and its alcohol percentage (ABV). Common examples: beer (12 oz, 5% ABV), wine (5 oz, 12% ABV), spirits (1.5 oz, 40% ABV).

Q2: How accurate is this calculator?
A: It provides a good estimate, but actual alcohol content may vary slightly by brand and serving.

Q3: Does container size affect standard drinks?
