Frequently Asked Questions
How is BAC estimated?
Using the Widmark formula: BAC% = (grams of alcohol ÷ (body-weight grams × r)) × 100 − 0.015 × hours, where r is a distribution ratio (about 0.68 for men, 0.55 for women).
Is this accurate enough to drive?
No. BAC varies with food, metabolism, medication and many other factors. In Bangladesh drink-driving is prohibited — if you have consumed any alcohol, do not drive.
