Blood Alcohol Calculator - BAC Calculator



Blood Alcohol Calculator


Alcohol is so easy to get in this era. You can literally order it online. Many drinkers don't know how much they actually consume, or how much it is impacting their behavior once they are intoxicated. Many states have started to lower their legal toxicity levels, because they've discovered the impact of simply consuming 1-2 drinks. Most people aren't aware of important is it to know your Blood Alcohol levels, or the fact that a blood alcohol calculator even exists! Our blood alcohol calculator will tell you about how to calculate your blood alcohol level, and why it's important to know your blood alcohol content.

What are blood alcohol levels?

This is a measurement of alcohol within your system. It's referred to as blood alcohol concentration, which is a % of alcohol which is in your bloodstream, or breath. Breathalyzers are great ways of finding out if you're legally intoxicated or not. There are several methods used to determine if your blood alcohol level is high. Blood alcohol concentration: Blood alcohol means the weight of ethanol in 100 milliliters of blood, 210 liters of breath.  It can be measured by your breath, blood, or urine. There are lots of indicators which show you're intoxicated, like being relaxed, impairment, irrational judgement, loss of memory, etc. As your blood alcohol level rises, does the effects of alcohol. Soon, your vision can become disoriented, or you could have difficulty hearing. Every person has a different state when they are intoxicated. It's difficult to figure out whether someone is intoxicated, buzzed, or needs help. Dangers of high BAC One of the dangers is vomiting, and choking. Even if you're awake, excess alcohol can cause you to lose physical control. At blood alcohol levels between .25 and .399 you are likely in need of medical attention, and have a blood alcohol level which indicates alcohol poisoning. The only way to lower your toxicity level is to simply rest. Time is the only way for blood alcohol levels to lower. For every hour, the blood alcohol level after the first drink is lowered by .015.  

What is the definition of one drink

One drink can vary depending on many factors. For example, one standard drink will depend on the type of alcohol and the alcohol content. 

For example, these are all the same when it comes to standard drinks

  • 12 oz can of beer

  • 5 oz glass of wine

  • 1.5 oz of distilled spirits

When you examine the amounts mentioned above, essentially each of these are equivalent to one drink due to their alcohol content. It takes much less volume of distilled spirit to count as a single drink due to the elevated alcohol content. Depending on what you’re drinking, “just one more drink,” can be enough to increase your BAC to an illegal level. 


Variables that affect your BAC

Gender: Females tend to have a higher blood alcohol content than men. Even if you are the same weight, and height, and drink the same amount - the female will have a higher BAC. This is due to the alcohol dispersed in body-water, and women have less water content than men. Women also have less of the enzyme in their body which breaks alcohol down than man. 

Weight: The more you weigh, the more water is in your body. The water dilutes the alcohol, which causes a lower BAC level. 

Age: This is another important factor. The older you get, the greater the impact alcohol has on your body. 

Rate of consumption: The faster you drink, the faster your BAC goes up, this is straightforward.

Food: If you drink on an empty stomach, it’ll result in your BAC going higher than if you drink while, or after, eating.

How can a BAC calculator help

IF you know your blood alcohol concentration, it can help you make smart decisions when you’re deciding whether to leave a bar, a restaurant, or a friend’s house. BAC calculators can help you determine if you are at near, or over, the legal BAC limit. Many calculators will require you to enter your gender, and your weight. 

What is the BAC limit in each state?

In all 50 states, .08% is the legal BAC limit. Most states have a zero tolerance level for underage drinking of .02% but New Jersey has a .01% limit. Other states like Alabama, Arizona, DC, Illinois, Maine, Minnesota, NC, and Oregon, have a zero tolerance level of .02%. Aggravated DUI, is a charge imposed when your BAC is higher than .08%. 

Types of tests used to understand your blood alcohol concentration

Field tests: If you’re pulled over due to a suspicion of dui/dwi, the officer can request you do physical tests to determine whether you’re impaired or not. This can mean touching your finger to the tip of your nose, walking in a straight line, etc. If you’re impaired by alcohol, you will probably have difficulty performing these activities.

Breathalyzer: These are portable tools used by law-enforcement when a DUI is suspected. Some breathalyzers can be problematic, if it runs on fuel cell sensors though it’s considered accurate for prosecution purposes. The breathalyzer is measuring the amount of alcohol in your breath. Individuals can purchase these tools too. 

Blood test: You have to give permission for a blood test to be done. You are in your rights to refuse a blood test to determine your BAC level. If you refuse, you could face stiff penalties like your license suspended, jail time, and fees. It’s typical for a blood test to be more accurate than a urine or breathalyzer test. 

Urine test: This is another method to measure your BAC. These are considered less accurate than blood tests/field sobriety tests. They are invasive and can’t be done via a traffic stop. Another issue is that alcohol can take up to 2 hours to show in urine, and remains in the system for up to 24 hours. It’s hard to determine if the BAC was above the legal limit at the time of the stop.
