Estimate your blood alcohol concentration (BAC) based on your weight, gender, the number of drinks you’ve consumed (beer, vodka, wine, etc.), and the time passed since you started drinking. Please note, this is an estimate and should not be used to determine if you are fit to drive or operate machinery.
Blood Alcohol Concentration (BAC) is a measure of the amount of alcohol in your bloodstream. BAC is usually expressed as a percentage, representing the grams of alcohol per 100 milliliters of blood.
Even at low levels, alcohol impairs judgment, reaction time, and motor skills. A BAC of 0.08% is the legal limit for driving in many countries. Please remember that BAC can vary based on individual factors and this calculator provides only an estimate.
