How much can you drink and not be legally drunk? It is something to think about as you head out to Fourth of July parties on Friday. The amount of alcohol in a person's body is measured by the weight of the alcohol in a certain volume of blood. Different factors affect your BAC including your gender, height, number of drinks and how fast you drink. Calculate your BAC here.
