## BMI Origins

B.M.I. 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

b m i Prime is a variation of the Quetelet index. Put simply, 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.

## The BMI Formula

How Body Mass Index is actually calculated

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

## BMI limitations

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