This calculator helps you figure out what your blood-alcohol content would be if you drank a specific number of drinks over a certain period of time. Remember, this is just an approximation. The calculator has to make certain assumptions, such as drinking all that alcohol on an empty stomach. If you eat while you drink, the alcohol is absorbed more slowly into your bloodstream.
Alcohol affects everyone differently. If you don't normally drink, a single beer could put you out of commission. For the most part, by the time you feel drunk, you're well past the legal limit.
In general, the more you weigh, the more you'd have to drink before you'd be considered drunk. Consider this: A 210-pound male could drink six beers in an hour and still not be legally drunk in many states. His blood-alcohol content would be 0.0984. If a 150-pound man drank the same amount, his blood-alcohol content would be 0.14258 - nearly 1½ times the legal limit.
Gender also affects your blood-alcohol content. The female counterpart to a 150-pound drunken male would have a blood-alcohol content of 0.17097 after consuming six drinks in an hour.
The slower you drink, the more time your body has to metabolize the alcohol. Each hour you add takes 0.012 off your blood-alcohol content, according to the formula the calculator uses.
