How accurate is this BAC calculator?

This calculator provides rough estimates based on the Widmark formula. Actual BAC can vary significantly due to metabolism, food intake, hydration, and individual differences. Do not rely on this for legal decisions.

What factors affect BAC?

BAC is affected by body weight, gender, alcohol content, number of drinks, time elapsed, metabolism, food intake, hydration, and individual physiology.

How long does alcohol stay in your system?

Alcohol metabolizes at about 0.015% BAC per hour on average. However, this rate can vary significantly between individuals.

What is the legal BAC limit?

Most countries have a legal driving limit of 0.08% BAC, but some have lower limits (0.05% or 0.02% for certain drivers). Always check local laws.

Can I speed up alcohol metabolism?

No, alcohol metabolism rate is largely determined by your liver and cannot be significantly sped up. Time is the only reliable way to sober up.
