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 standard BMI formula:

Where:

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

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 should not be the sole 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 accurate results, measure your height without shoes and weight in light clothing.
