With Blood Alcohol Calculator you can quickly and easily calculate your blood alcohol content (BAC) by entering a few basic pieces of information. First create user profiles for you and your friends by entering your name weight and gender. Once you've created a user you can add drinks to that user by selecting one of hundreds of built-in drinks or by creating your own custom drinks by adding that awesome cocktail you made at home or that tasty microbrew you just discovered. Lastly enter how long you've been drinking and calculate the blood alcohol content of you and your friends. This includes a decimal representation of your blood alcohol content (BAC) (Such as 0.08) some possible side effects related to that blood alcohol range as well as a detailed graph letting you know what your blood alcohol content (BAC) will be over time.
