PI – Ponderal Index Calculator

What is a ponderal index calculator?

The Ponderal Index (PI) calculator is a simple tool for calculating your ponderal index and checking your weight classification based on age, weight, and height.

What is the ponderal index?

The Ponderal Index (PI), also known as the Corpulence Index or Rohrer's Index[1], is a better version of the body mass index (BMI) that also helps you check your weight classifications, whether underweight, normal, overweight, or obese.

It uses a mathematical formula that calculates your relative body mass based on height and weight. To get your PI, take the cube root of your weight, divide it by height, and multiply the result by 100. [2]
