Columbia residents will have the opportunity to check their blood alcohol content Friday evening at Tenth Street and Broadway. As part of the Know Your Limit event, police will use a breath-testing device to make residents aware of the amount of alcohol consumption it takes to reach certain limits.

Blood alcohol level is calculated by determining how many milligrams of alcohol are present in 100 milliliters of blood. This chart shows the blood alcohol content after a certain number of drinks in one hour for males and females of various body weights.
