The alcohol concentration is expressed per breath volume of how many liters?

Explanation:
Breath alcohol concentration is reported using a fixed volume of exhaled air so results are comparable across tests and individuals. The standard volume used is 210 liters of breath, so the result is expressed as grams of alcohol per 210 liters of breath. This standard aligns with the way breath alcohol relates to blood alcohol through the blood–breath partition ratio (about 2100:1), allowing the breath result to reflect the underlying BAC in a consistent way. Other volumes aren’t used because they wouldn’t provide that common reference point.
