1. What Is a Bmi Calculator?

The BMI (Body Mass Index) calculator is a simple tool that estimates body fat based on a person's weight and height. It provides a numerical value that helps categorize individuals into underweight, normal weight, overweight, or obese categories.

2. How Does the Calculator Work?

The calculator uses the BMI formula:

Where:

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

Explanation: The formula divides a person's weight by the square of their height to produce a standardized measurement of body composition.

3. Importance of BMI Calculation

Details: BMI is a quick screening tool for potential weight problems in adults. It helps identify individuals who may be at risk for weight-related health issues.

4. Using the Calculator

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