Blood

(BAC)
Calculator
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
following
formula
may
be
of
some
help.
In
the
UK,
BAC
is
reported
as
milligrams
of
alcohol
per
100
millilitres
of
blood.
For
example,
a
BAC
of
0.08%
is
legally
given
as
a
limit
of
80
mg
per
100
ml.
It
is
also
reported
in
grams
per
Litre,
which
is
an
equivalent
measurement
The
University
of
Oklahoma
Police
Department
have
answered
several
of
the
general
misconceptions
that
people
have
on
how
much
they
can
drink
and
legally
drive.
Below
is
the
list
they
have
set
out
including
questions
regarding
eating
mints
before
a
breath
test
and
eating
certain
foods
before
breath
tests.
They
also
have
designed
a
BAC
test
to
see
how
much
you
would
be
over
the

driving
limit
taking
into
consideration
weight,

General Misconceptions about Drink Driving
"If I have too much to drink, I can drink a lot of coffee to sober
up quickly. Right?"
Ha. Tell us another one! Drinking a lot of coffee after drinking
too much alcohol may, however, increase your discomfort through
the need to use the bathroom while being transported to the jail
on DUI charges. Only time reverses impairment.
"Will eating breath mints after drinking fool a police 'breath test'?"
Eating mints will not affect your BAC level since it isn't the smell
of your breath, but the alcohol content, that's measured. Using
breath mints, however, may earn you points with the arresting officer
if you normally have bad breath.
"Well, at least eating breath mints might fool the officer, right?"
Ha. Sure, police are really fooled when they see a combination of
erratic driving behavior and powerfully minty breath. Yep, that
one fools us every time. Get real.
"I've heard preparing yourself by eating certain foods before
an evening of heavy drinking will help keep your sober. Is that
true?"
That story has been around since before your grandparents were born.
The only relation we've seen between what you eat before drinking
and your drunkenness is that the more you drink, the more likely
we are to find what you ate on your shirt, or on the floorboard
of the patrol car.
"Ok, but if I eat a BIG meal before drinking, won't that help keep
me from getting drunk?"
How much you have eaten, and how recently, may have a small effect
on how quickly or slowly the alcohol you consume will enter your
bloodstream — but it won't stop the alcohol from entering. If you
drink too much, you will become intoxicated. There may be, however,
a direct correlation between the size of your meal and how much
of your meal may be found later in patrol cars and jail cells.
"Will splashing cold water on my face or taking a cold shower
help sober me up?"
Splash away! And by all means, take a cold shower. It may make you
cleaner, but it won't sober you up or make you a safe driver. The
deputies at the jail, however, prefer clean drunks and recommend
showering prior to doing anything that will lead to your arrest,
such as driving after you've been drinking.
"Will running around the block a few times sober me up enough
to drive home?"
Exercise won't sober you up any faster, but feel free to run around
the block as many times as you like. The deputies at the jail ask
us to remind you to shower after your long run and before you drive
a car.
"They were serving a spiked punch, but I couldn't even taste
the alcohol in it. I can't be drunk!"
Party-goer, beware. Fruit juices have the ability to mask the taste
of alcohol. A fruit "punch" can contain a substantial amount of
alcohol without the taste of the alcohol being noticed — but it
will make you just as drunk as alcohol which you can taste in another
kind of drink. A mild-tasting cup of punch at a party may contain
more alcohol than any normal drink you would buy at a bar.
