Impairment begins with one drink. Many factors can affect a person's blood alcohol content (BAC), including amount of alcohol consumed, rate of consumption, food consumption, and factors specific to each person such as gender, age, weight, height and metabolism.

The Alcometer provides rough estimates of blood alcohol content for an average person only. This information is intended for educational purposes only and is NOT LEGAL ADVICE.  Do not rely on this information to drive or to work.  Never drink and drive.

The Alcometer is provided "as is" without warranty of any kind, whether expressed or implied. All implied warranties, including, without limitation, implied warranties of merchantability, fitness for a particular purpose, and non-infringement, are hereby expressly disclaimed.

The Alcometer uses updated Widmark formula to calculate BAC. You can find out more about methodology in the research paper
