About

Blood Alcohol Content (BAC) Calculator is an online tool that estimates the concentration of alcohol in your body and shows how long it will take to sober up. However, keep in mind that the results are only approximate and this alcohol calculator can in no way be evidence of sobriety.

How does it work

The results of this Blood Alcohol Content Calculator are obtained by calculating the ratio between consumed alcohol content, its strength and human's weight. Gender differences are taken into account as well. The algorithm was based on the fact that the consumed alcohol evenly distributes in the fluid in the body, which makes up 50-65% of the total human weight. However, there are many other factors that this calculator cannot take into account, so the results are only approximate.
