BAC Calculator

The BAC calculator should not be used to determine whether or not you are safe to drive.  It is not fool proof and is merely provided for you to get a “reality check” on the BAC the police officer says the machine registered when you were arrested for DWI.

The Intoxilyzer 5000EN is used to determine a subject’s blood alcohol concentration, which is commonly referred to as the BAC.  In New Hampshire, it is illegal to drive while impaired or with a BAC of .08% or greater.  For people under the age of 21, the BAC level is even lower; .02% or higher is DWI.

There are many factors that the Intoxilyzer <span style=”text-decoration: underline;”>does not</span> take into consideration when calculating your BAC, including gender, age, body fat percentage, quantity and type of food consumed and hematocrit levels.

While the Intoxilzyer doesn’t account for these variables and many others, it is still carries a great amount of weight in front of a jury or judge and you are presumed to be DWI if the machine says your BAC is a .08% or greater.

Alcohol affects people differently. Your subjective feelings of impairment may not be reflected by your true BAC.  Remember that different types of drinks contain varying amounts of alcohol so it is important to keep those factors in mind when trying to calculate your BAC.  To be safe, never drink and drive and always bring a designated driver along to ensure everyone arrives home safely.

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 concentration (“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.

It would be extremely foolish for us
to pretend that our “Drink Wheel” can tell you what your BAC actually is, first because it would open us up to an incredible amount of potential liability and second if it really did work accurately there would be no need for anyone to buy the instruments that we make and sell.

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.
