Applications
Educational tool for estimating your Blood Alcohol Content (BAC) based on how many drinks you've had over time. Useful for understanding alcohol metabolism and knowing when you might be impaired.
The Formula
Uses the Widmark formula: BAC = (Alcohol consumed in grams / (Body weight in grams x r)) x 100 - (0.015 x time in hours), where 'r' is a gender constant (0.68 for males, 0.55 for females).
Fun Fact: Your liver can process approximately 1 ounce of liquor (or one standard drink) in one hour. If you consume more than this, your system becomes saturated, and the additional alcohol will accumulate in the blood.
