BAC Calculator (Blood Alcohol Content)
The BAC Calculator is a tool which can help you assess the concentration of alcohol in your blood. The calculation is based on what kind of alcohol you drank, how much of it you consumed and how long ago. As your blood alcohol concentration depends on a variety of aspects, this sobriety calculator takes into consideration your body weight and sex as well. Have you ever considered why one person gets drunk more easily than another? Or wondered how this changes depending on the weight, sex, or type of alcohol? If so, keep reading.
How to use blood alcohol calculator?
To find out what your blood alcohol content actually is, you only need to fill the blanks with the number of beers, wine glasses and/or vodka shots you drank. Do not ask friends, the calculator can only work with the exact amount that you drank. If you can't, you don't need to assess it, you are certainly drunk. When you have done that, plug in your weight, sex and the time when you started drinking. The BAC Calculator will estimate the percentage of your blood comprised of alcohol.
Let’s take an example:
- Large beers:
3 - Wine glasses:
0 - Vodka shots:
5 - Body weight:
90 - Sex:
male - Started drinking:
8 hrs ago
The calculator shows your blood as 0,6% alcohol.
You can also use the advanced version of the calculator, which contains an additional “raw alcohol” input. You can either fill it with the amount of alcohol you drank, typing it in grams, or fill in the first three blank fields and the calculator will display your raw blood alcohol content. For our 3 large beers and 5 vodka shots, which we have plugged in, we get 165 grams of raw alcohol.
Why use the drunk calculator?
Sometimes after drinking alcohol you feel horrible. If this is the case, then you are still under the influence of alcohol. However, not everyone's hangover as a disaster. In such a situation, you may want to drive home in the morning (or afternoon), but are unsure if the breathalyser test would show any alcohol content in your blood. That's why you can use the BAC Calculator to measure your blood alcohol concentration before you set off. However, it's worth confirming the result with another tool like store bought breathalyser test, which can be found in most pharmacies.
You can use the drunk calculator to appease your curiosity or to compare your result with those of your friends. If you are interested in other calculators related to the topic, you should take a look at our BMR calculator and wedding alcohol calculator.
Sobriety calculator
This blood alcohol calculator can not only be used to check the concentration of alcohol in your blood right now, but also to estimate when your blood alcohol content is going to equal 0. This is when you're fully sober again - it might be longer than you imagine! This number is presented below your current blood alcohol level. Thanks to this function you can find out how much time you need to get a particular amount of alcohol out of your system, and how it varies depending on the type of drinks you consume.
How BAC affects your behavior
It is good to know how exactly a certain concentration of alcohol affects your organism, especially if you're trying to estimate when it will be okay to drive again.
