Metabolic Mathematics
The core engine behind NeonBAC is not based on guesswork, but on nearly a century of forensic toxicology. Every simulation our scanner runs is rooted in the mathematical principles established by Swedish physician Erik M.P. Widmark in the early 20th century.
In 1932, Widmark published his seminal work on the kinetics of alcohol distribution. He discovered that ethanol does not stay confined to the blood but distributes itself throughout the total body water. This insight allowed for the creation of a reliable predictive model that remains the global standard for legal and medical alcohol reconstruction.
Calculates peak concentration by balancing dosage (A) against body mass (W) and distribution (r), minus metabolism over time (H).
Biological and mathematical inputs that drive the peak BAC and elimination trajectory.
This represents the total weight of alcohol consumed in ounces. Because different beverages have varying ABV (Alcohol by Volume) percentages, NeonBAC converts your drink log into pure ethanol weight before running the calculation.
Widmark identified that gender and body composition drastically change how alcohol is diluted. Men typically have a higher body water percentage (r = 0.73), while women typically have a lower ratio (r = 0.66) due to higher average adipose tissue. This "r" factor is why weight alone cannot predict BAC.
This is the rate at which the liver eliminates alcohol. While it can vary, the average rate of 0.015% per hour is the unyielding "downward slope" of the metabolic timeline. No amount of coffee or cold showers can alter this biological constant.
While Erik Widmark used pen and paper, the NeonBAC engine uses these same equations to generate thousands of data points instantly. By simulating the "rising" absorption phase and the "linear" elimination phase, we provide a forensic-grade look at your metabolic journey.

While it is the global forensic standard, it provides a high-probability estimate. Individual variables like hydration, specific medications, or underlying health conditions can cause minor deviations from the statistical average.
This is a mathematical constant used to align liquid ounces of consumed alcohol with the total weight of blood in the human body (measured in pounds) to produce a decimal percentage result.
Metabolism is an active process that begins shortly after consumption. Subtracting elapsed time multiplied by the Beta Constant (0.015) accounts for the volume of alcohol the liver has already successfully eliminated from the system.
NeonBAC simulations are mathematical estimates based on forensic averages (The Widmark Formula). Individual metabolism varies based on hydration, food intake, and biological health. These results are for educational and research purposes only.
NEVER USE THIS TOOL TO DETERMINE YOUR LEGAL ABILITY TO DRIVE. IF YOU HAVE CONSUMED ALCOHOL, DO NOT OPERATE A VEHICLE OR HEAVY MACHINERY.
