1. What is BMI?

BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women. It is a simple and widely used screening tool to identify weight categories that may lead to health problems.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)

Explanation: The formula converts height from centimeters to meters by dividing by 100, then calculates the square of height in meters, and finally divides weight by this squared height value.

3. Importance of BMI Calculation

Details: BMI provides a quick assessment of weight status and helps identify potential health risks associated with being underweight, overweight, or obese. It is used by healthcare professionals as a screening tool for weight-related health issues.

4. Using the Calculator

Tips: Enter weight in kilograms and height in centimeters. Ensure both values are positive numbers. For accurate results, measure weight without heavy clothing and height without shoes.
