BAC Calculator & Drink Chart

The BAC Calculator will help roughly estimate your BAC level based upon time, weight and amount of alcohol consumed. Do not rely on this chart if you are trying to avoid being arrested for DUI. The general rule is to not drive after consuming alcohol; the safest way to avoid a DUI.

One Drink:

= One bottle of beer (12 oz.)
= One glass of wine (6 oz.)
= One “single” drink (1ΒΌ oz. of liquor)

DUI Drink Calculator

The BAC Calculator, or drink chart, above does not consider other important variables that contribute to your overall BAC level. Each person processes alcohol differently, so you cannot compare your BAC level to your friend’s using this calculator. Some factors that impact your BAC level include: lack of sleep, food intake, over the counter drugs, prescription medication. Do not rely strictly upon the BAC Calculator above. You still can be arrested for DUI even if your BAC level is below the legal limit. You cannot use this chart as a defense if you are charged with a DUI.

Also, it is not uncommon for people to forget exactly how much alcohol they have consumed. Sometimes recollection and math become impaired with every drink, so use this chart with great caution.

One must pay attention to the alcohol content of their drink and the exact amount consumed. Many people confuse the “one drink” per hour rule. Read more about the one drink per hour rule.
