1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight to screen for weight categories that may lead to health problems. It provides a reliable indicator of body fatness for most people.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

Explanation: BMI compares your weight to your height to estimate body fat. Higher BMI values generally indicate higher body fat.

3. Importance of BMI Calculation

Details: BMI helps healthcare professionals screen for potential weight problems in adults. While not diagnostic, it can indicate whether further assessment is needed.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For accurate results, measure height without shoes and weight in light clothing.
