1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared. This calculator converts kg to lbs and cm to inches for the calculation.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ BMI = \frac{weight\ (lbs) \times 703}{height\ (inches)^2} \]

Where:

\( weight \) — Weight in pounds (converted from kg)
\( height \) — Height in inches (converted from cm)
703 — Conversion factor

Explanation: The formula correlates fairly well with body fat percentage for most people, though it has limitations.

3. Importance of BMI Calculation

Details: BMI provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.

4. Using the Calculator

Tips: Enter weight in kilograms and height in centimeters. All values must be valid (weight > 0, height > 0). The calculator will automatically convert to pounds and inches for the calculation.
