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.

When a person consumes alcohol and alcoholic beverages they will
go through a process of absorption and elimination of the alcohol.
The process by which alcohol moves from the stomach into the blood
is known as absorption. Alcohol consists of small molecules which
easily pass through the human body and are completely soluble in
water. Thus, when it enters the stomach, about 20 percent of the
alcohol ingested is absorbed directly through the stomach walls, while
the remaining 80 percent passes through the base of the stomach into
the small intestines where it is actively absorbed and enters the blood

Each drink, if it is a normal drink such as a 12 ounce beer or one and
a half ounces of hard liquor, will elevate a person's blood alcohol
level by anywhere from .015 to .02 percent.  The legal limit in
California is .08 percent.  Given these amounts, the average person
will elevate to approximately .08 with as few as 3-4 drinks.  Each
drink, remember, will raise your BAC by about .01 to .02.

Once in the blood stream, the alcoholic beverages are quickly
distributed to other tissues and organs (especially the brain) where the
alcohol is retained in direct proportion to the amount of water in the
tissue or organ. Relative to total body water, only a small amount of
the total alcohol consumed is in the blood, breath, or urine. Body
water acts as a reservoir for alcohol and the loss of blood from an
injury (e.g., traffic collision) will not appreciably change the BAC

Most of the alcohol a person drinks is eliminated by chemical
oxidation in the liver. A small portion (approximately 2-10 percent) of
the alcohol consumed is not metabolized and eliminated through other
pathways such as urination, respiration, and perspiration. The rate of
elimination (excretion) varies between individuals, and can even vary
from time to time for the same person. However, after reaching peak
value, an average person’s BAC will decline approximately 0.015
percent per hour.  

With these basic formulas one can estimate their true BAC by
multiplying the number of drinks by .02 and subtracting roughly .015
to .02 per hour for elimination.  If arrested for a DUI, contact a
Burbank Drunk Driving Lawyer to assist you in Court.

In many dui cases, the prosecution will bring in an expert to estimate
your true BAC at the time of driving.  This estimation is often
referred to as a retrograde extrapolation.  This practice us questioned
as unreliable.
