What is the BAC Calculator & How does it work?
Blood Alcohol Content (BAC) is a measure of the percentage of alcohol in your blood. It’s calculated using the amount of alcohol consumed, your body weight, and the time elapsed since drinking began.The formula to calculate BAC is: BAC = (A – D) / (r * W), where A is the total alcohol consumed in grams, D is the amount of alcohol removed from the body over time, r is the distribution ratio (typically 0.73 for men and 0.6 for women), and W is your body weight in kilograms.
BAC = \frac{A – D}{r * W}
A = total alcohol consumed (g)
D = alcohol removed over time (g)
r = distribution ratio
W = body weight (kg)
D = alcohol removed over time (g)
r = distribution ratio
W = body weight (kg)
