1. What is BMI?

BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women. It provides a simple numeric measure of a person's thickness or thinness.

2. How Does the Calculator Work?

The calculator uses the BMI formula:

\[ BMI = \frac{weight_{lbs} \times 703}{(height_{cm} / 2.54)^2} \]

Where:

\( weight_{lbs} \) — Weight in pounds (lbs)
\( height_{cm} \) — Height in centimeters (cm)
703 — Conversion factor
2.54 — Centimeters to inches conversion

Explanation: The formula converts height from cm to inches, then calculates the ratio of weight to height squared.

3. Importance of BMI Calculation

Details: BMI is a simple screening tool that can indicate whether a person is underweight, normal weight, overweight, or obese. It helps assess health risks associated with weight.

4. Using the Calculator

Tips: Enter weight in pounds (lbs) and height in centimeters (cm). All values must be valid (weight > 0, height > 0).
