1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared. 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 determine if you're underweight, normal weight, overweight, or obese.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive screening tool for weight categories that may lead to health problems. It helps identify potential weight problems for adults.

4. Using the Calculator

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