BMI Prime

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
Bmi Prime is a variation of the Quetelet index. If you have a Prime of less than 0.74, you are underweight. If your prime is more than 0.74 and less than 1.00, your weight is ideal. If your BMI prime is more than 1 you are defined as being overweight.

Do the sums

  • BMI = 703 . weight(pounds) / height2 (inches2)         (Imperial Units)
