Enter the weight and height into the calculator to determine the Corpulence Index. This calculator can also evaluate any of the variables given the others are known.

Corpulence Index Formula

The following formula is used to calculate the Corpulence Index.

CI = (W / (H^2)) * 703


  • CI is the Corpulence Index
  • W is the weight in pounds (lbs)
  • H is the height in inches (in) 703 is the conversion factor from lbs/in^2 to kg/m^2

To calculate the Corpulence Index, divide the weight in pounds by the square of the height in inches. Multiply the result by 703 to convert the units from lbs/in^2 to kg/m^2. The result is the Corpulence Index, a measure of body fat based on weight and height.

What is a Corpulence Index?

A Corpulence Index, also known as Body Mass Index (BMI), is a numerical value derived from a person’s weight and height. It is used to assess whether a person has a healthy body weight for a given height. It is calculated by dividing a person’s weight in kilograms by the square of their height in meters. The index is used to categorize individuals as underweight, normal weight, overweight, or obese, providing a rough indicator of body fatness. However, it does not directly measure body fat.

How to Calculate Corpulence Index?

The following steps outline how to calculate the Corpulence Index (CI).

  1. First, determine the weight in pounds (W).
  2. Next, determine the height in inches (H).
  3. Next, square the height (H^2).
  4. Next, divide the weight by the squared height (W / (H^2)).
  5. Finally, multiply the result by 703 to calculate the Corpulence Index (CI = (W / (H^2)) * 703).

Example Problem:

Use the following variables as an example problem to test your knowledge.

Weight (W) = 180 lbs

Height (H) = 70 inches
