1. What Is Body Mass Index Calculator?

The Body Mass Index (BMI) Calculator is a tool that estimates body fat based on height and weight measurements. It provides a simple numeric measure that helps categorize individuals into different weight status categories.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

Explanation: BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters. The result provides a standardized measure of body composition.

3. Importance of BMI Calculation

Details: BMI is widely used as a screening tool to identify potential weight problems in adults. It helps assess health risks associated with underweight, overweight, and obesity, though it doesn't directly measure body fat percentage.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. Ensure accurate measurements for reliable results. The calculator will provide your BMI value and corresponding weight category.
