Calculate your ponderal index also known as corpulence index or rohrer's index with this simple calculator. Ponderal Index is more accurate compared to the Body Mass Index.

This calculator is used to calculate your ponderal index also known as corpulence index or rohrer's index. Ponderal Index is more accurate compared to the Body Mass Index.
(NOTE: For an infant, you can use the crown-heel length for height field.)
Ponderal index otherwise called as corpulence index or Rohrer's index. This index combines an individual's weight and height and results an index value for classifying the body weight as normal or abnormal. Ponderal index is considered as an improvement over BMI (Body Mass Index). The reason being, BMI considers body as a two-dimensional square, where as ponderal index considers the body as a three-dimensional cube. BMI uses a single formula for adults and infants, whereas PI uses slightly different formula for infants compared to the adult formula. Let's see the formulas used to calculate PI.
PI = mass ÷ height3
|Less than 8||Severe Underweight|
|8 - 11||Underweight|
|11 to 15||Normal|
|15 to 17||Overweight|
|17 and above||Obese|
|2.2 - 3||Normal|
