Alcohol / BAC Calculator

BAC Levels and Effects:

• 0.00-0.03%: No significant effects – sober
• 0.03-0.06%: Mild relaxation, slight euphoria – impaired judgment
• 0.06-0.10%: Reduced coordination, slower reaction time – legally impaired in most places
• 0.10-0.20%: Significant impairment, slurred speech, poor coordination – clearly intoxicated
• 0.20-0.30%: Severe impairment, confusion, nausea – alcohol poisoning risk
• 0.30%+: Potential loss of consciousness, life-threatening – requires medical attention

Note: The legal limit for driving is 0.08% in most US states and 0.05% in many other countries.

Factors That Affect BAC:

• Body weight: Heavier people generally have lower BAC from the same amount of alcohol
• Gender: Women typically reach higher BAC levels than men with the same alcohol consumption
• Food intake: Eating before or while drinking slows alcohol absorption
• Rate of consumption: Drinking quickly results in higher peak BAC
• Alcohol strength: Higher ABV drinks increase BAC more quickly
• Medications: Some medications can interact with alcohol and increase impairment
• Tolerance: Regular drinkers may show fewer signs of impairment at the same BAC

Remember that impairment begins well before the legal limit, and everyone metabolizes alcohol differently.
