1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = 703 × lb/in² where lb is a person's weight in pounds and in is their height in inches.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

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

Where:

\( weight \) — Weight in pounds (lb)
\( height \) — Height in inches (in)
703 — Conversion factor (kg/m²)/(lb/in²)

Explanation: The formula converts weight in pounds and height in inches to the standard BMI metric (kg/m²).

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 pounds and height in inches. All values must be valid (weight > 0, height > 0).
