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 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
How Our BAC Calculator Works
Our calculator helps you:
- Find out how drunk you might be right now
- See how long until the alcohol leaves your body
- Learn what might happen at your BAC level
- 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.
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)
- Under 21: 0.00% or 0.02% in most states
- Truck drivers: 0.04% limit
Even under 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.
