How to Calculate Blood Alcohol Level

The scientific way of calculating blood alcohol levels is simple; you take the proportion of alcohol to blood and that is your blood alcohol concentration. Most people will only experience their blood alcohol being tested in the worst of circumstances. However, the science is universal and therefore there are many resources now available that allow individuals to calculate their own blood alcohol level. Personal breathalyzers can be purchased at many corner drug stores. Even more interesting are the online tools to calculate blood alcohol level (by entering your weight) and number of drinks, there are sites that claim to be able to tell you your tolerance. Most people, however, would be perfectly happy to never have to calculate their blood alcohol level—not drinking and driving can make this possible.
