How To Calculate Your BAC For One Hour Of Drinking:

  2. From left to right, each square represents one drink.
  3. The first dark line to the right indicates a BAC of .04, which indicates impairment.
  4. The second dark line to the right indicates a BAC of .10, which is considered legal intoxication or "drunk" in most states.

To Calculate Your BAC Over A Longer Period Of Time:

  1. Add the total amount of drinks consumed.
  2. From that total, subtract 1 drink for each hour of drinking. In other words, your body will burn off 1 drink per hour.
