How Much is Too Much?

- 1/10/2019

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. Use the BAC Chart, below to calculate your BAC levels.

Keep in mind that it's illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of .08 and above in all states. The calculations provided here may not represent your true BAC and should not be relied on as an indicator of whether you are capable of driving. Without belaboring a point made many times before, the best approach is to avoid driving after you drink.
