Female Blood Alcohol Concentration


The chart below it the blood alcohol concentration chart for females (the male blood alcohol level chart can be found a here.) Now, using the chart find the intersection between your weight and the number of drink you are planning to have or have had. For this chart, one drink is considered to be the standard serving sizes:

  • 1¼ oz. of 80-proof liquor
  • 12 oz. of beer
  • 4 oz. of table wine

When you have found your number on the chart, write it down. This number indicates the female blood alcohol blood concentration if you had a certain number of standard drinks all at one time. Once you have found your female blood alcohol concentration, continue your final calculation below, which corrects for the amount of time that has past since your first drink.

Since most people don't have all their drinks at one time, there is a correction factor, which considers time - how long you have been drinking for.

To adjust for the time, determine the number of hours for which you have been drinking. For every hour, subtract .015% from the value you have written down. This final number is an estimate of your female blood alcohol concentration.

Example: A 120 pound woman has 4 drinks in two hours. The value on the chart, where 120 lbs intersects "4" is .15, indicating that she would have a 0.15% blood alcohol concentration had she had all the drinks at once. To factor in the time that has past, we subtract 0.015%*2 (0.03%) from 0.15%, to leave us with 0.12% blood alcohol concentration. This woman is well above the legal limit for driving and should not be driving a car!
