How to Use the Blood Alcohol Content (BAC) Calculator

This Blood Alcohol Content (BAC) Calculator is designed to estimate your blood alcohol concentration and assess your legal driving status. Follow the step-by-step guide below to use the calculator effectively.

Step 1: Enter Your Gender

  • Locate the Gender field.
  • Click on the dropdown menu and select your gender: Male or Female.
  • This selection helps determine the alcohol distribution ratio in your body.

Step 2: Enter Your Weight

  • Find the Weight (lbs) field.
  • Input your weight in pounds. Make sure it’s within the required range of 80 to 400 lbs.
  • This value is essential for calculating how alcohol is distributed in your body.

Step 3: Enter Number of Drinks Consumed

  • Proceed to the Number of Drinks field.
  • Enter the number of standard drinks you have consumed. The number should be between 0 and 50.
  • Each drink is assumed to contain a specific amount of alcohol, which this calculator measures.

Step 4: Enter Alcohol Percentage

  • Look for the Alcohol Percentage (%) field.
  • Input the alcohol percentage of the beverages consumed. It should be a value between 0 and 100%.
  • This indicates how much of your drink is pure alcohol.

Step 5: Enter the Time Passed Since First Drink

  • Locate the Hours Since First Drink field.
  • Input the number of hours that have passed since you had your first drink, ranging from 0 to 48 hours.
  • This helps adjust your BAC level as the body metabolizes alcohol over time.

Once you have filled all the input fields, the calculator will present you with the following results:

  • Blood Alcohol Content (BAC): This value represents your estimated BAC as a percentage, accurate to three decimal places.
  • Hours Until Sober: This field estimates the number of hours it will take for your BAC to return to 0.00%, displayed to one decimal place.
  • Legal Driving Status: This field provides a message indicating whether you are legally permitted to drive. However, driving is not recommended if you have consumed alcohol.
