BAC is expressed in terms of grams of alcohol in every how many milliliters of blood?

Blood Alcohol Concentration (BAC) is a measure used to determine the amount of alcohol present in an individual's bloodstream. Specifically, BAC is expressed in grams of alcohol per 100 milliliters of blood. This standard measurement is widely used because it provides a convenient assessment of an individual's level of intoxication relative to safety and legal limits.

Understanding this metric is vital for law enforcement and public safety. The use of a 100-milliliter standard allows for consistent reporting and enforcement of laws regarding driving under the influence and related matters. Hence, the concentration of alcohol in terms of 100 milliliters is crucial for evaluating impairment and compliance with legal thresholds.
