What is BAC?

BAC (Blood Alcohol Content) is the percent of alcohol in the blood system. There are various means of determining BAC. An absolute level can be obtained only by drawing a sample of blood. The most reliable estimate can be obtained via very accurate breathalyzers that take a sample of alveolar (deep lung) air.  Below is a rough estimate of a person’s BAC.

About the Drink Wheel

The Intoximeters Inc. “Drink Wheel”¹ is a form that you can fill out. Upon completion we will instantly compute your estimated blood/breath alcohol content (“BAC”) based on the information that you have provided and return that estimate to you. It is presented as a public service to Intoximeters web site visitors. Its primary purpose is to provide useful information about the responsible use of alcohol.

Why is it called a “Drink Wheel”?

We call it the “Drink Wheel” because it is based on various paper and cardboard BAC calculators that are given out in alcohol awareness programs, some of which are in the form of a wheel that you can spin around to calculate your estimated BAC based on what and how much you have had to drink.

Disclaimer

The “Drink Wheel” cannot tell you exactly what a persons exact BAC  because a person’s actual BAC is dependent on many complex factors, including their physical condition (body composition, health etc…) and what they have recently ingested (including food, water, medications and other drugs). This site includes a more detailed discussion of the Pharmacology and Disposition of alcohol in humans.

The results that are generated are rough estimates of an average healthy person’s BAC assuming typical beverage sizes, recipes and alcohol content. The BAC estimates generated by the Drink Wheel should not be used to infer anyone’s fitness to work, drive or perform any other task or duty.
