How It Works
This calculator uses the widely accepted Widmark Formula to estimate Blood Alcohol Concentration (BAC).
- Alcohol Consumed: Total grams of alcohol ingested. We use standard drink sizes (14g per standard drink).
- Weight & Gender (r): The distribution constant `r` is typically 0.68 for men and 0.55 for women due to differences in body water percentage.
- Metabolism (-0.015 × Hours): The average human body metabolizes alcohol at a rate of roughly 0.015% BAC per hour.
IMPORTANT DISCLAIMER: This tool provides an estimate for informational and educational purposes only. Actual BAC depends on many factors including metabolism, food consumed, hydration, and genetics. Do not use this tool to determine if it is safe to drive. Never drink and drive.

Widmark Formula
\text{BAC} = \left( \frac{A \times 5.14}{W \times r} \right) - 0.015 \times H
- BAC: Blood Alcohol Content (%)
- A: Total alcohol consumed in ounces
- W: Body weight in pounds
- r: Gender constant (0.73 for men, 0.66 for women)
- H: Hours elapsed since first drink
Frequently Asked Questions
The Blood Alcohol Calculator uses established biological and physical formulas to estimate key health metrics, providing a baseline understanding of your fitness or nutritional status.
The Blood Alcohol Calculator uses standard global formulas (like WHO guidelines). However, generic formulas cannot account for individual variations in muscle mass, bone density, or ethnic genetic differences. It serves as an estimate, not a diagnostic tool.
Never. The Blood Alcohol Calculator is strictly for informational and educational purposes. You should always consult a licensed healthcare professional before making any significant changes to your diet, exercise, or medical routine.
For tracking trends, using the Blood Alcohol Calculator once every few weeks under consistent conditions (e.g., same time of day) is generally more useful than daily tracking, which can fluctuate due to hydration and other temporary factors.
If the globally recognized formula for the Blood Alcohol Calculator requires age and gender inputs to be accurate, those fields will be provided. If not, the metric is universally calculated regardless of demographics.
Yes, your privacy is our priority. The Blood Alcohol Calculator processes all your data locally on your device. We do not collect, store, or share your personal health inputs.
While the Blood Alcohol Calculator is useful for the general population, elite athletes often have unique body compositions that require clinical-grade measurements (like DEXA scans) rather than generalized algorithmic estimates.
