Basic blood alcohol level charts typically display estimated blood alcohol concentration in correlation to body weight and the number of drinks consumed. Some charts define low-risk drinking as maintaining less than .06 percent blood alcohol concentration, and display the general number of drinks per hour compared to body weight.
Most charts display body weights ranging from 100 to 240 pounds and the effects of up to 10 drinks. Some blood alcohol level charts display nuances that may influence individual outcomes, such as gender. Some charts include types and sizes of drinks to standardize the chart calculations, and some charts also include potential outcomes at various blood alcohol concentration levels.
