What is a BAC Calculator?

A BAC calculator tells you how drunk you might be. BAC means "Blood Alcohol Content." It shows how much alcohol is in your blood.

The calculator looks at:

  • How many drinks you had
  • How strong your drinks were
  • How long you've been drinking
  • How much you weigh
  • If you're a man or woman
BAC is written like 0.08%. This means 0.08% of your blood is alcohol. It is enough to fundamentally change how your brain functions. If that number ever reached just 1%, you would be likely dead. In fact, for most people, 0.40% (less than half of 1%) is already likely to cause a coma.

How Our BAC Calculator Works

Our calculator helps you:

  1. Find out how drunk you might be right now
  2. See how long until the alcohol leaves your body
  3. Learn what might happen at your BAC level
  4. Make better choices about driving

We use math that scientists trust. But remember - this is just a guess. It's not perfect like real police tools.

This calculator can't replace real breathalyzer machines that police use. Always be extra careful when deciding if you can drive after drinking.

Legal BAC Limits

In most US states, 0.08% BAC is the legal limit for driving. If you're above this, you can get arrested.

  • Utah: 0.05% (stricter than other states)
  • Truck drivers: 0.04% limit
  • Under 21: 0.02% or even 0% in most states

Under any of these limits, alcohol hurts your driving. You start getting worse at driving with your very first drink. That's why the punishment for drunk driving can be very serious - jail time, big fines, and losing your license.
