Blood Alcohol Content (BAC) Calculator

Q: 7. Is the Vedantu BAC calculator accurate?

The Vedantu BAC calculator provides an estimate of your Blood Alcohol Content based on the widely used Widmark formula. It's important to remember that individual factors can influence the accuracy of the result. The calculator should not be used as a definitive measure and should not replace professional medical advice.

How to Calculate Your BAC Step by Step

What is BAC Calculator?

A BAC Calculator is a helpful tool that estimates your Blood Alcohol Content (BAC) based on your gender, body weight, the number of drinks you've had, and the time since you started drinking. It provides a quick way to understand your current alcohol level and impairment risk.

This calculator helps you make safe, informed decisions by showing whether you may be over the legal driving limit. It is especially useful for students, partygoers, and anyone wanting to track their sobriety responsibly.

Formula Behind BAC Calculator

The calculator uses the Widmark formula: BAC = (Alcohol Consumed in grams / [Body Weight in grams × r]) × 100 – (elimination rate × hours). Here, r is a constant: 0.68 for males, 0.55 for females. This estimates your current BAC considering both intake and metabolism.

BAC Example Conversion Table

Scenario	Estimated BAC (%)
Male, 70kg, 4 drinks, 2 hours	~0.07%
Female, 60kg, 2 drinks, 1 hour	~0.04%
Male, 80kg, 6 drinks, 3 hours	~0.10%
Female, 50kg, 4 drinks, 2 hours	~0.13%
Male, 60kg, 1 drink, 1 hour	~0.02%
