In addition, the blood alcohol content (BAC) calculator is only an estimate and not sufficiently accurate to be considered legal evidence. The calculations are averages. Individuals may vary in their personal alcohol tolerance. Food in the stomach, medication, health, and psychological conditions are influencing factors.  Many establishments that serve alcohol serve portions larger than the standard drink size. If in question, request to know the volume of alcohol in a drink from the server.

A person's blood-alcohol level is the result of a complex interaction of weight, gender, alcohol consumed and time. Any amount of alcohol will impair your ability to drive or operate other machinery.
