← すべてのツールBAC Calculator
Estimate your Blood Alcohol Content (BAC) based on consumption and body weight.
Alcohol affects every person differently based on their size, gender, and how quickly they consume drinks. Understanding your Blood Alcohol Content (BAC) is vital for safety and legal compliance. While no online tool can replace a professional breathalyzer or provide a legal guarantee of sobriety, our BAC Calculator uses the scientifically recognized Widmark Formula to provide an estimate of how much alcohol is currently in your bloodstream. Remember: when in doubt, never get behind the wheel.
使い方
The tool uses the Widmark Formula, which calculates alcohol concentration based on the mass of alcohol consumed and the patient's body water (determined by weight and gender), then subtracts the average rate of metabolism over time.
Calculation Examples
1. **Moderate**: A 80kg male who has 3 beers over 2 hours will have an estimated BAC of **~0.03%**.
Why use this tool in your daily life?
Responsibility starts with information. This tool helps you understand how different drinks affect your unique physiology, empowering you to make safer choices for yourself and your community.
