What is a BAC calculator?

A BAC calculator estimates your Blood Alcohol Content based on inputs like weight, gender, number of standard drinks and time. It provides an educational estimate, not a legal measurement.

Is the BAC estimate accurate?

It uses the Widmark formula and typical metabolism rates. Individual physiology, medications, and food intake can cause significant variation. For legal or safety-critical purposes, use a certified test.

Do you store my data?

No. All calculations run in your browser and are not uploaded or stored on our servers.

What is a standard drink?

In the U.S., one standard drink contains about 14g of pure alcohol: 12oz beer (5%), 5oz wine (12%), or 1.5oz spirits (40%).

What is the legal BAC limit?

In most U.S. states, the per se limit for non-commercial adult drivers is 0.08 BAC; many countries have different limits. Younger drivers and commercial drivers often have lower limits.

How long until I am sober?

A typical elimination rate is about 0.015 BAC per hour, but this varies. Our tool shows an estimate of time to reach 0.00 BAC.
