BAC Chart Values
.00 - .05 - Normal behavior, no impairment, mostly sober
.05 - .10 - Possibly buzzed, euphoria, lessened inhibitions
.10 - .15 - Lightly drunk, feeling good, smiling
.15 - .20 - Definitely drunk, possibly an upset stomach
.20 - .30 - Confused, nauseated, feels shitty
.30 - .35 - Throwing up, passing out, falling over
.35 - .40 - Way too drunk, coma
Anything over .40 - Way, way too drunk — death
Notes
- When typing in a custom percent alcohol, keep in mind that the proof of an alcohol is about double the percent (ie - 80 proof alcohol is 40%)
- If you’re typing in a mixed drink, only count the number of shots you put in — not the drink’s total volume
- It’s impossible to be extremely accurate in estimating a BAC — everyone is different
- Being legal to drive assumed you are 21 years old and the legal limit is .08
- All calculations are based on the math presented by the US Department of Transportation. Please visit this website if you’d like to see the logic behind the math, or even if you want more details regarding the calculations.

4 typical mixed drinks in one hour = 0.451?
no.
Depends on how strong the drink is. If you’ll note the percent alcohol, you have to type in the number of shots into the drink, not the actual volume of the drink. For example, if you had a “typical mixed drink” with 2 shots, you’d type in (2) single shot(s), rather than the entire volume of your mixed drink.

Please note that I just made a bugfix to the Javascript — the calculator was making an incorrect conversion to kilograms (if kilograms were selected). The bug is fixed now.
I removed ‘typical mixed drink’ from the drinks list — it was unclear whether you add the volume of the mixed drink or the volume of the alcohol added. To calculate mixed drinks, just add in the volume of alcohol added.
You should amend this program to account for different laws in different countries. The legal limit in many parts of the world is 0.05, not 0.08 like in the USA, so you could be liable for a lawsuit for giving misleading information in the “time until you can drive” column. Failing that, you need to add a legal disclaimer.
Inaccurate. Th heavier the drinker you are the slower alcohol metabolizes in your system. You won’t *feel* drunk sooner because of higher tolerance.
While it is true that alcohol tolerance increases, the hepatic metabolism of alcohol also increases. Over time, a heavy drinker will be able to clear more alcohol per hour than a normal drinker because a heavy drinker’s liver will induce more enzymes to break down alcohol.
Great calculator, good layout

Great page. Could you go into more detail on the metabolic rates you have listed to choose from. Can the human body actually metabolize alcohol that fast ie: “frat boy”
Hi,
My company does occasional breathalyser checks, due to 0.00% tolerance.
A mail was sent out today, regarding someone being fired because they were 0.25% over the limit. However, they didn’t say which unit of measurement was used. Is B.A.C always used for breath tests ?
Thanks,
Chris
