1. What is BMI Calculation?

BMI (Body Mass Index) is a simple calculation using a person's height and weight to assess body weight relative to height. It provides a numeric value that helps categorize individuals as underweight, normal weight, overweight, or obese.

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 value that correlates with body fatness.

3. Importance of BMI Calculation

Details: BMI is a quick screening tool to identify potential weight problems in adults. It helps assess risk for weight-related health problems and is used by healthcare professionals worldwide.

4. Using the Calculator

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