The Blood Alcohol Concentration (BAC) Calculator provides an estimate of your alcohol level using the widely accepted Widmark Formula. By inputting your body weight, gender, the number of drinks consumed, and the time elapsed, this tool calculates a theoretical BAC percentage. This is a crucial tool for understanding how alcohol metabolizes in your body and estimating the time required to return to sobriety.
