PETH Test Calculator
The PETH test calculator helps estimate blood alcohol concentration (BAC) based on alcohol consumption, body weight, and time elapsed. Medical professionals and individuals use it to assess intoxication levels, determine safe driving limits, and make informed decisions about alcohol consumption.
Formula:
BAC = (Number of drinks × 0.06) / (Weight in kg × 0.68) - (0.015 × Hours since last drink)
Reference Table
| Weight (kg) | Drinks | Hours | BAC Range |
|---|---|---|---|
| 60 | 2 | 2 | 0.03-0.05 |
| 70 | 3 | 3 | 0.04-0.06 |
| 80 | 4 | 4 | 0.05-0.07 |
FAQs
How does the PETH test calculator work?
The calculator uses a scientific formula considering weight, alcohol consumption, and time to estimate blood alcohol concentration. It applies metabolic rates and absorption factors to provide approximate BAC levels, helping users understand their intoxication status.
Is the PETH calculator accurate?
While based on scientific formulas, actual BAC can vary due to metabolism, food intake, and health conditions. The calculator provides estimates and shouldn't replace professional testing or legal decisions.
