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

Variables:

- 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).

- First, determine the weight in pounds (W).
- Next, determine the height in inches (H).
- Next, square the height (H^2).
- Next, divide the weight by the squared height (W / (H^2)).
- 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
