1. What is Body Mass Index?

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It is a simple, inexpensive screening method for weight categories that may lead to health problems.

2. How Does the Calculator Work?

The calculator uses the BMI formula:

\[ BMI = \frac{weight_{kg} \times 703}{height_{in}^2} \]

Where:

\( weight_{kg} \) — Weight in kilograms
\( height_{in} \) — Height in inches
703 — Conversion factor for kg and inches to BMI

Explanation: This formula calculates BMI using weight in kilograms and height in inches, with the conversion factor 703 to adjust for the units.

3. Importance of BMI Calculation

Details: BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems. It helps identify potential weight-related health risks.

4. Using the Calculator

Tips: Enter weight in kilograms and height in inches. All values must be valid (weight > 0, height > 0). For accurate results, measure weight and height without shoes and in light clothing.
