How to Estimate Blood Alcohol Content
Formula
The Widmark formula estimates BAC based on alcohol consumed, body weight, gender, and time. The body metabolizes alcohol at approximately 0.015% BAC per hour.
This is an estimate only. Actual BAC depends on many factors including food intake, medications, hydration, and individual metabolism.
Common use cases:
- Responsible drinking awareness
- Understanding impairment levels
- Educational alcohol safety
