Be Responsible About Drinking publishes blood alcohol level charts on BRAD21.org. The organization's charts highlight the corresponding blood alcohol levels for a range of zero to 10 drinks, based on different body weights.
Be Responsible About Drinking provides charts for both men and women, and indicates the lowest blood alcohol levels at which an individual's driving skills may be affected by their consumption. Moreover, the website also indicates the points at which the government considers drinkers to be legally intoxicated, and the blood alcohol levels at which they are at risk of death.
BloodAlcoholCalculator.org allows a user to submit his state of residence, weight, the hours during which he has been drinking, and the number of each type of drink. The site then returns an estimate of the user's blood alcohol level.
