The Ponderal Index (PI) or Corpulence Index (CI) is similar to BMI in that it measures the leanness or corpulence of a person based on their height and weight. The main difference between the PI and BMI is the cubing rather than squaring of the height in the formula. The output is a measure.

Details

Note that normally height input should be in meters for the Ponderal Index, but in consistency to the other functions of befitteR height takes the input in centimeters. The calculation is based on the following equation:

PI = \frac{weight}{height^{3}}

For adults, a value of 12 is considered normal.
