  • Educational articles and guides about blood alcohol content

The service is provided free of charge. No account or registration is required. The calculator is accessible via standard web browsers on desktop and mobile devices.

Disclaimer of Warranties

This calculator provides estimates only for educational and informational purposes.

The calculations and results provided by this website:

  • Are not a substitute for actual blood alcohol testing (breathalyzer or blood test)
  • Are not medical advice and should not be relied upon for health decisions
  • Are not legal advice regarding impaired driving laws or charges
  • Are not professional advice of any kind
  • Should never be used to determine if you are safe or legal to drive

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that the service will be uninterrupted, error-free, or that defects will be corrected. We do not warrant the accuracy, reliability, or completeness of any calculations or information provided.

Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL BLOOD ALCOHOL LEVEL CALCULATOR, ITS OPERATORS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO:

You use this calculator entirely at your own risk. We are not responsible for any decisions, actions, or outcomes based on calculator results. The only safe choice after consuming alcohol is not to drive.

Accuracy

We strive to provide accurate calculations based on established scientific formulas and methodologies, specifically the Widmark formula which is widely used in forensic toxicology. However:

  • All results are estimates based on population averages
  • Individual factors (metabolism, food consumption, medications, health conditions) significantly affect actual BAC
  • The calculator uses standard drink definitions that may not match actual drink contents
  • We do not guarantee the accuracy of any calculation or result

The formulas, constants, and methodology used are documented on our About page. Reference data is derived from publicly available scientific sources.
