NOTES:

This chart assumes a highly conservative elimination rate of alcohol from the body of 0.015 mg/100 ml/hr. Rates may vary between 0.01 and 0.025 mg per 100 ml/hr.

Chart assumes at least one drink per hour. Under most social drinking conditions, drinks are consumed every 20 minutes or at a rate of three per hour in a one to two hour period. Patterns will change with extended periods of drinking.

Chart is based on the maximum BAC attainable per drink which may not occur during periods of extensive drinking or during the consumption of food with alcohol.

Blood alcohol percentages on the charts have been truncated to two decimals.
