Blood Alcohol Content (BAC) Calculator

Blood alcohol content (BAC), also called blood alcohol concentration or blood alcohol level is commonly used as a metric of alcohol intoxification. BAC levels represent the percent of a person's blood that is concentrated with alcohol. For instance, a BAC of .01 means that 1% of a person's bloodstream contains alcohol.  

In South Carolina, it is illegal to operate a vehicle with a BAC above .08 or 8%.
Drivers under the age of 21 are held to stricter standards under zero tolerance laws. In SC, the zero tolerance BAC limit is .02 or 2%.  

BAC Calculator
The BAC table below provides an accurate estimation of an individual's BAC at a certain period in time. However, like any other BAC table it cannot provide results with 100% accuracy due to the many variables (age, gender, weight, alcohol amount, alcohol percentage, time) utilized in determining one's BAC.
