Blood alcohol concentration calculator
Calculate an estimate of how long it will take for your body to metabolise the alcohol you have ingested.
Remember that there can be large individual differences in the elimination of alcohol from the body, and the result of the calculator may not match the values given by a breath test. If you are in doubt, take a breath test. The responsibility is always yours.
What kinds of drinks did you have? Either report the types of drinks or the number of servings directly. You can adjust the values using the plus and data-minus buttons or by typing a value in the field.
