1. What is the Corpulence Index?

The Corpulence Index (CI) is a measure of body fat based on weight and height. It was developed in the UK as an alternative to BMI, using a cubic relationship between weight and height rather than a quadratic one.

2. How Does the Calculator Work?

The calculator uses the Corpulence Index formula:

Where:

• \( Weight \) — Body weight in kilograms (kg)
• \( Height \) — Height in meters (m)

Explanation: The index calculates body mass per unit volume, providing a three-dimensional assessment of body size compared to BMI's two-dimensional approach.

3. Importance of Corpulence Index

Details: The Corpulence Index provides an alternative measure of body composition that may be more accurate for certain populations. It's particularly useful in clinical settings where a cubic relationship between weight and height might better represent body fat distribution.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0). For accurate results, use precise measurements.

5. Frequently Asked Questions (FAQ)

Q1: How does CI differ from BMI?
A: CI uses a cubic relationship (weight/height³) while BMI uses a quadratic relationship (weight/height²). CI may provide a better representation of body volume.

Q2: What are normal CI values?
A: Normal CI values typically range between 12-15 kg/m³ for adults, though this can vary based on age, gender, and population.

Q3: When was the Corpulence Index developed?
A: The Corpulence Index was developed in the UK as an alternative to BMI, with research dating back several decades.

Q4: Are there limitations to CI?
A: Like all anthropometric measures, CI doesn't distinguish between fat and muscle mass, and may not be appropriate for all populations.

Q5: Should CI replace BMI?
A: CI provides an alternative perspective but hasn't replaced BMI in most clinical settings. Both measures have their uses depending on the context.
