Blood Alcohol Calculator
Use this calculator to see how your drinking during a night out affects your blood-alcohol level, and how that compares to the DUI limit according to your state's laws.
This calculator takes into account your weight, gender, time you'll be out, drinks you'll consume, and state laws to determine how you can stay under the DUI limit. Please keep in mind, however, that you should always take precaution before getting behind the wheel to protect the safety of yourself and others. People are affected by alcohol differently, and it may be unsafe for you to drive even if you're under your state's DUI limits.
If you feel safe driving after a few drinks, also keep in mind that the most routine DUI conviction is guaranteed to cost you thousands of dollars and mar your record for years. And it will drive up your car insurance rates for just as long.
