1. What is BMI?

BMI (Body Mass Index) is a measure that uses your height and weight to determine if your weight is healthy. It's calculated by dividing your weight in kilograms by your height in meters squared.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

Explanation: The formula provides a simple numeric measure of a person's weight relative to their height.

3. Importance of BMI Calculation

Details: BMI is a screening tool that can indicate whether a person is underweight, healthy weight, overweight, or obese. It helps assess potential health risks associated with weight.

4. Using the Calculator

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