BMI History

Body Mass Index Prime is method of using the results of the BMI calculations to quickly and easily rank a person into a category. Eg:
  • BMI Prime less than 0.74 = Underweight.
  • BMI Prime greater than 0.74 and less than 1.00 = Optimal weight.
  • BMI Prime greater than 1 = Overweight
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

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

BMI calculations do not differentiate between muscle mass and fat mass.
