The "Alcotest" program for calculating the maximum alcohol content of the breath is a handy tool for any driver, especially those who have to take an alcohol test before driving. The calculation is based on the law of mass conversion and uses the mass spectrometric method to determine the alcohol content of the breath.

In this program, the user can set the amount of alcohol (in grams) that corresponds to the desired blood alcohol level. Then, the user can set the time period (in seconds) for which the blood alcohol level should be monitored. The user can select the time period manually or by the beep warning. After selecting the desired time period, the user can select the volume of the blood (in milliliters). The user can also enter the amount of weight (in kilograms). Then, the user can press the button "Solve".

The "Solve" button will display the solution for the given parameters.
