5 things worth knowing about your body mass index (BMI) and the BMI Calculator

1. BMI is the abbreviation for body mass index.

2. In the last couple of decades, BMI was frequently criticized, although this index has been used since the middle of the 19th century. Mathematicians of the Oxford University claim that the formula distorts reality and it is worth using a factor of 1.3 for the calculation. It corrects the fact that the standard BMI index evaluates taller people to be thicker while shorter ones to be thinners.

3. The classic body mass index does not show your body fat percentage.

4. The general formula of BMI index is not applicable to children. In general, the formula gives a plausible result over the age of 20, while it strongly distorts reality under the age of 18.

5. The formula used for the calculation of your body mass index is as follows: BMI index = weight (kg) / height 2 (m)
