Frequently Asked Questions (FAQ)

Our Blood Alcohol Calculator is based on the proven Widmark Formula (learn more about the formula), which calculates blood alcohol content (BAC) based on personal information and consumed beverages. You enter your gender, body weight, the quantity and type of beverages consumed, and the drinking period. The calculator accounts for alcohol elimination over time to provide the most accurate estimate of your current blood alcohol level.
The Blood Alcohol Calculator provides an estimated calculation of your blood alcohol content based on the data entered. However, accuracy can be influenced by individual factors such as metabolic rate, health condition, diet, and drinking habits. Therefore, the calculator should not be used as a legally binding measurement method. For precise results, it is recommended to use official alcohol tests.
Several factors can influence your blood alcohol content, including:
  • Gender: Women often have a higher blood alcohol content than men with the same alcohol intake.
  • Body Weight: A higher body weight can lower blood alcohol content.
  • Alcohol Elimination: The body eliminates alcohol at an average rate of about 0.1 to 0.15 BAC per hour.
  • Type and Quantity of Consumed Beverages: Different beverages contain varying amounts of alcohol and calories.
  • Eating Habits: Having a meal before or while drinking can slow down alcohol absorption.
