Blood Alcohol Calculator

Estimate your Blood Alcohol Content (BAC) level

IMPORTANT DISCLAIMER

This calculator provides rough estimates only and should NOT be used to determine if you are safe to drive or operate machinery. BAC varies based on many factors including food intake, medications, health conditions, and individual metabolism. Never drink and drive. When in doubt, use a designated driver, taxi, or rideshare service. This tool is for educational purposes only.

BAC Reference Chart

BAC Level	Effects
0.00-0.02%	No apparent effects, normal behavior
0.02-0.05%	Mild relaxation, slight mood changes

Important Safety Information

- Legal BAC limits for driving vary by country (typically 0.05-0.08%)
- Even low BAC levels can impair driving ability
- Food slows alcohol absorption but does not prevent intoxication
- Only time can reduce BAC - coffee, cold showers, etc. do not help
- Alcohol affects individuals differently based on tolerance, medications, and health
- If someone shows signs of alcohol poisoning (confusion, vomiting, seizures, slow breathing), call emergency services immediately
