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. It provides a reliable indicator of body fatness for most people.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

\[ BMI = \frac{weight\ (kg)}{[height\ (m)]^2} \]

Where:

\( weight \) — Body weight in kilograms
\( height \) — Height in meters

Explanation: BMI is calculated by dividing weight in kilograms by the square of height in meters. The result is then categorized into standard weight status categories.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive screening tool for weight categories that may lead to health problems. For most adults, BMI provides a good estimate of body fatness.

4. Using the Calculator

Tips: Enter weight in kilograms, height in meters, age in years, and select gender. All values must be valid (weight > 0, height > 0, age between 1-120).
