What is Blood Alcohol Concentration (BAC) and How is it Measured?
Blood Alcohol Concentration (BAC) is a metric used to quantify the amount of alcohol present in the bloodstream. It is typically measured in grams of alcohol per deciliter of blood. BAC levels are used to assess impairment and legal intoxication, with different countries setting varying legal limits for activities such as driving. Breathalyzers and blood tests are common methods for measuring BAC.
