BAC Chart & Estimate Uncertainty | The BAC Calculator
EDUCATIONAL BAC EXPLORER
This educational chart repeats the site’s Widmark-style arithmetic across time. It is not a BAC test, a sober-time prediction, or a decision tool for driving or work.
If alcohol is involved, do not use a web result to decide whether to drive.
This table shows fixed model arithmetic only. It cannot tell you your actual BAC, whether alcohol is absorbed, or whether you are safe to drive.
Choose a sober ride after drinking. This page cannot give driving clearance.
Online estimates depend on reported drinks, label accuracy, timing, weight and a simplified formula. Food, absorption, metabolism, health, medication, body composition and drinking pattern can all make an actual measurement differ.
