Blood Alcohol Calculator (BAC)

Here is a calculator to give you an idea of what your BAC is in different circumstances. By entering your weight, what you drank, and over how long you drank, you can get an estimate of your blood/breath alcohol content. You should know that this is a rough estimate and is not intended to provide legal advice. The results should not be used to infer your ability to drive or perform any task.
