About Disclaimer
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. Courtesy of Intoximeters,

Here is some information that Wikipedia has
on BAC:
Blood alcohol content (BAC) or blood alcohol
concentration is the concentration of alcohol in blood. It is
usually measured as mass per volume. For example, a BAC of 0.02%
means 0.2 ‰ (permille) or 0.02 grams of alcohol per 100 grams
of individual's blood, or 0.2 grams of alcohol per 1000 grams of
blood. Blood alcohol concentration is measured in so many different
units that it can be extremely confusing.
The number of drinks consumed is a very poor measure of
intoxication largely because of variation in physiology and
individual alcohol tolerance. However, it is generally accepted that
the consumption from sober of two standard drinks (containing a
total of 20 grams) of alcohol will increase the average person's BAC
roughly 0.05% (a single standard drink consumed each hour after the
first two will keep the BAC at approximately 0.05%), but there is
much variation according to body weight, sex, and body fat
percentage. Furthermore, neither BAC nor the number of drinks
consumed are necessarily accurate indicators of the level of
impairment. Tolerance to alcohol varies from one person to another,
and can be affected by such factors as genetics, adaptation to
chronic alcohol use, and synergistic effects of drugs.
Alcohol content in blood can be directly measured by a hospital
laboratory. More commonly in law enforcement investigations, BAC is
estimated from breath alcohol concentration (BrAC) measured with a
machine commonly referred to as a Breathalyzer which is a
genericized trademark.
Legal
limits
For purposes of law enforcement, BAC is used to define
intoxication and provides a rough measure of impairment. Although
degree of impairment may vary among individuals with the same BAC,
BAC can be measured objectively and is therefore legally useful and
difficult to contest in court. Most countries disallow operation of
motor vehicles and heavy machinery above prescribed levels of BAC.
Operation of boats and aircraft are also regulated.
Limits by country (BAC: Blood Alcohol
Content)
The alcohol level at which a person is considered to be legally
impaired varies by country. The list below gives limits by country.
These are typically BAC (blood alcohol content) limits for the
operation of a vehicle.
