BMI, sometimes known as the Quetelet index, is a measure used to estimate a person's body shape based upon a person' weight and height. It originated in Belguim around the 1840's by Adolphe Quetelet. It is a simple calculation based on the individual's body weight divided by the square of their height. ## The simple maths

This is how BMI is calculated

- BMI = weight(kilograms) / height
^{2} (metres^{2}) (Metric Units) - BMI = 703 . weight(pounds) / height
^{2} (inches^{2}) (Imperial Units)

BMI calcs ignore variation in physical characteristics.
