BMI Origins

BMI Prime is simple way of defining a single figure that is not immedieately related to any other units of measurement, but which can quickly and easily rank a person into a category. :Eg:
  • BMI Prime < 0.74 = Underweight
  • BMI Prime > 0.74 and < 1.00 = Optimal weight.
  • BMI Prime > 1 = Overweight

How it's calculated

You can use the following formula to calculate your BMI :
  • BMI = weight(kilograms) / height2 (metres2)         (Metric Units)
  • BMI = 703 . weight(pounds) / height2 (inches2)         (Imperial Units)

BMI limitations

BMI is proportional to the mass and inversely proportional to the square of the height. So, if all body dimensions double, and mass scales naturally with the cube of the height, then BMI doubles instead of remaining the same. This results in taller people having a reported BMI that is uncharacteristically high, compared to their actual body fat levels.
