1. What Is Blood Alcohol Concentration?

Blood Alcohol Concentration (BAC) is a measure of the amount of alcohol in your bloodstream. It is expressed as a percentage and is used to determine legal intoxication levels and assess impairment.

2. How Does The Calculator Work?

The calculator uses the Widmark formula:

Where:

• \( Alcohol \) — Total alcohol consumed in grams
• \( Weight \) — Body weight in kilograms
• \( r \) — Distribution ratio (0.68 for males, 0.55 for females)

Explanation: The formula estimates BAC based on the amount of alcohol distributed throughout body water, which varies by gender due to differences in body composition.

3. Importance Of BAC Calculation

Details: Knowing your BAC helps understand impairment levels, make informed decisions about driving, and assess alcohol metabolism. Legal driving limits are typically 0.08% in most jurisdictions.

4. Using The Calculator

Tips: Enter total alcohol consumed in grams, your weight in kilograms, and select your gender. Remember this is an estimate and doesn't account for food consumption, metabolism rate, or time elapsed.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this BAC calculator?
A: This provides an estimate based on the Widmark formula. Actual BAC can vary due to metabolism, food intake, hydration, and individual differences.

Q2: What is the legal BAC limit for driving?
A: In most countries, the legal limit is 0.08%, but some regions have lower limits (0.05% or 0.02% for commercial drivers).

Q3: How long does alcohol stay in your system?
A: The body metabolizes alcohol at about 0.015% per hour on average, but this varies by individual.

Q4: Can I use this for medical purposes?
A: No, this calculator is for educational purposes only. For medical or legal matters, use professional breathalyzers or blood tests.

Q5: Why is the r factor different for men and women?
A: Women typically have higher body fat percentage and lower water content, leading to higher BAC from the same amount of alcohol.
