The alcohol calculator provides an approximation of how alcoholic drinks of different alcohol contents increase the blood alcohol content. The calculator also provides an estimate of the amount of energy in the drinks.
The calculator is based on population averages and is therefore unreliable when calculating the values of an individual. There are major individual differences in how alcohol is metabolised.
The blood alcohol content can be accurately measured only with a breathalyser.
Have you ever wondered how much energy you consume when you drink? The amount of energy in alcohol is almost the same as in fat, which is a lot. One gram of fat has 9 kcal, and one gram of alcohol has 7 kcal. A single unit of alcohol in a restaurant has roughly 15 grams of alcohol.
