1. What is BMI?

BMI (Body Mass Index) is a measure that uses your height and weight to work out if your weight is healthy. The BMI calculation divides an adult's weight in kilograms by their height in meters squared.

2. How Does the Calculator Work?

The calculator uses the BMI formula:

Where:

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

Explanation: BMI provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.

3. Importance of BMI Calculation

Details: BMI is a useful screening tool to identify potential weight problems in adults. However, it's not a diagnostic tool as it doesn't directly measure body fat.

4. Using the Calculator

Tips: Enter your weight in kilograms and height in meters. For most adults, BMI provides a good estimate of weight-related health risks.
