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 — Measured in kilograms (kg)
• Height — Measured in meters (m)

Explanation: The formula divides your weight in kilograms by your height in meters squared. This gives a standardized measure that can be compared across different heights.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive screening method for weight category - underweight, healthy weight, overweight, and obesity. It helps identify potential weight problems in adults.

4. Using the Calculator

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