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 formula
The formula below is used to measure BMI
- BMI = weight(kilograms) / height2 (metres2) (Metric Units)
- BMI = 703 . weight(pounds) / height2 (inches2) (Imperial Units)
BMI limitations
