How long does it take to sober up?
AlcoCalc estimates when its model reaches zero. It cannot tell when a person is actually sober or fit to drive.
Feeling sober is not a measurement
How you feel is not an objective measure of alcohol in your body. The calculator shows a mathematical estimate, not an individual biological measurement.
Why the result is an estimate
The model spreads drinks evenly across the time period. In reality, you may drink them earlier or later, and a cocktail’s alcohol strength varies by recipe.
What the remaining time means
The estimate is based on assumptions about absorption and elimination. When the countdown reaches zero, it still does not confirm that your actual blood alcohol level is zero.
