Best blood-alcohol calculator I've seen so far. It takes into account variables such as how much food in the stomach, rate of metabolism, etc.
Seldom needed, but really useful - Especially those who drink not regularly have little feeling of their alcohol level. It's good to know when you will be sober again, so you can plan your drinking in advance. The effect of every drink can be seen in advance.
Very useful. I use this all the time when I'm out with my friends!
