Blood Alcohol Content (BAC) refers to the level of alcohol in a person's bloodstream. When you submit to a breath test, you agree to allow the administrator of that test to measure your BAC. The BAC of two people who consume the same amount of alcohol over the same time period may have vastly different results due to height, weight, body fat, sex and whether or not the alcohol was consumed on an empty stomach. A breath test is not a foolproof method of determining BAC. You may have questions about the reading you produced with regard to the alcohol consumption that led up to it. Simply input your information below, and this calculator will give you a ballpark reading of what your BAC should have been in a particular circumstance.
