Note: This calculator is a generic estimate that does not consider such factors as differences in male or female metabolism, health, or diet. In other words, you mileage will almost certainly vary. It is no way purports to be, nor should it be relied upon to be a guideline for how much you can drink and still safely drive or avoid being arrested.
