Blood Alcohol Content Calculator

Estimate Your Blood Alcohol Content

You can use this calculator to estimate the level of alcohol in your system, or your blood alcohol content. The calculator uses the Widmark formula to determine your level of intoxication.

In North Carolina, it is illegal to operate a motor vehicle with a blood alcohol content of 0.08 or higher. However, if you feel any effect from drinking at all, do not drive.
