Formula Used
Standard Drink Definition
A standard drink is defined as 14 grams of pure alcohol, which is approximately:
- 12 ounces of beer (5% alcohol)
- 5 ounces of wine (12% alcohol)
- 1.5 ounces of distilled spirits (40% alcohol)
Safe Consumption Calculation
The calculator uses the following formula to determine safe alcohol consumption:
Maximum standard drinks = (Weight in pounds × Tolerance factor) / 2
Where the tolerance factor is:
- 0.6 for women with low tolerance
- 0.7 for women with medium tolerance
- 0.8 for women with high tolerance
- 0.7 for men with low tolerance
- 0.8 for men with medium tolerance
- 0.9 for men with high tolerance
Important Notes
These calculations provide general guidelines. Individual responses to alcohol can vary significantly. Always drink responsibly and never exceed these limits if you plan to drive or operate machinery.
Interpreting Your Results
Your results will show you the maximum number of standard drinks you can consume safely based on your inputs. Here's what each result means:
| Result Range | Interpretation | Recommendation |
|---|---|---|
| 1-3 standard drinks | Low consumption | Safe for most people, but consider your overall health |
| 4-6 standard drinks | Moderate consumption | Generally safe, but monitor your intake |
