BAC Calculator: Blood Alcohol Levels Chart

What Is BAC?

The definition of bac is blood alcohol concentration. The other descriptions are blood alcohol level or blood ethanol level.

This is one of the most common ways to measure the percentage of alcohol present in the body and the way this percentage may affect the behavior of the person. However, the level of impairment may vary for individuals even with the same level of BAC.

Note that only the blood test may show the most accurate results of ethanol in the bloodstream. Urine and breath tests are less reliable, but can still show the relatively correct results. BAC calculators shall not be considered a replacement for such examinations and shall be used for informational purposes only. This is a rough estimation that does not take into consideration some crucial factors, including individual metabolic rates, amount of food in the stomach, or personal health issues like alcohol addiction.

Measurement type

Results:

* One standard drink is:

  • 12 ounces of regular beer, which is usually about 5% alcohol
  • 5 ounces of wine, which is typically about 12% alcohol
  • 1.5 ounces of distilled spirits, which is about 40% alcohol

** Please note that these BAC calculator values are only estimates and that no one should rely solely on these results. The BAC chart does not take into consideration all the factors that can influence the alcohol rate of absorption by the body, such as sex of the drinker, body fat percentage, health issues, metabolism, drinking frequency or medication. There is no alcohol level chart that is 100% accurate because they differ from individual to individual. If you have consumed alcohol, the best thing to do is not get behind the wheel..

BAC And Impairment Levels

BAC levelEffects From Alcohol
BAC 0.00 – 0.03At this level there is no loss of coordination, this is the legal bac for driving in most states, but the individual might feel mildly relaxed, a little lightheaded, loss of shyness and slight euphoria. The inhibitions also start to loosen slightly, and the mood the individual was before starting drinking will be mildly intensified.
BAC 0.04 – 0.06At this alcohol level, judgment, memory, and reasoning begin to be impaired. The individual is less cautious, feels relaxed, and less inhibited. Sadness and happiness are felt more intensely, and the behavior might become exaggerated.
BAC 0.07 – 0.09At this bac level, some people have a feeling of euphoria, with caution and self-control being reduced. The individual is prone to riskier behaviors because memory, reason, and judgment do not function properly.
BAC 0.10 – 0.12The individual feels euphoric. The motor skills, balance, coordination, memory, and judgment are markedly impaired. Some people become belligerent, aggressive or loud, and emotions are exaggerated.
BAC 0.13 – 0.16At this level of alcohol in blood, the individual is very drunk with severe impairment of major motor skills, perception, and judgment. The reaction time is prolonged, the speech is slurred, and vision is blurred.
BAC 0.17 – 0.19Most drinkers will start to feel incapacitated, and some will pass out. Trying to focus on an object becomes very difficult, and nausea starts to set in.
BAC 0.20The individual is dizzy, confused, disoriented, and needs help to walk or stand. Vomiting and nausea set in, but because the gag reflex is impaired, the individual might choke on their vomit.
BAC 0.25At this level, all sensory, physical, and mental functions are dramatically impaired. There is an increased risk of injury caused by accidents and falls, as well as choking on own vomit.
BAC 0.30The individual might no longer realize where he is or recognizing the individuals around him. There is the possibility of suddenly passing out and being difficult to awaken. The body becomes unresponsive to almost all stimuli.
BAC 0.40This level is life-threatening to almost anyone reaching it. Complete unconsciousness and even coma might set in. 0.40% BAC is similar to the level of anesthesia. In extreme cases, death might occur. The higher levels might be called a lethal bac.
