BAC Calculator

Blood Alcohol Content (BAC) Calculator


Estimated BAC Levels Based on Consumption
1. NUMBER OF DRINKS:


2. WHAT ARE YOU DRINKING?


3. HOW MUCH DO YOU WEIGH?:


4. HOW MANY HOURS HAVE YOU BEEN DRINKING?


RESULT:
—YOUR BLOOD ALCOHOL CONTENT...
BAC %: (THEORETICAL)

Analysis:
*All states have passed a .08 per se law. The final one took effect in August of 2005. 

Important Note: There is no blood alcohol calculator that is 100% accurate because of the number of factors that come into play regarding the consumption and reduction (burnoff) rates of different people. Factors include the sex (male/female) of the drinker, differing metabolism rates, various health issues and the combination of medications that might be taken, drinking frequency, amount of food in the stomach and small intestine and when it was eaten, elapsed time, and others. The best that can be done is a rough estimation of the BAC level based on known inputs.

Is your weight or beverage option not shown on this calculator? The basic formula for estimating blood-alcohol concentration is available from The National Highway Traffic Safety Administration.

Disclaimer: This is in no way purported to be a guideline for how much you can drink and still drive or avoid being arrested! The best policy is don't drink and drive. Period.

What's your DUI.Q?

 

Drink as a group, be responsible as a group

When you're out with friends, you're not just responsible for yourself. If you suspect that anyone in your group is impaired, join together to keep that person from driving.
