1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight to assess body fatness. It's commonly used to screen for weight categories that may lead to health problems.

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 relates weight to height squared, providing a standardized measure of body size.

3. Importance of BMI Calculation

Details: BMI is a quick screening tool for weight categories that may indicate potential health risks. It helps identify underweight, normal weight, overweight, and obesity.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For muscle gain tracking, remember BMI doesn't distinguish between muscle and fat mass.

5. Frequently Asked Questions (FAQ)

Q4: Does BMI apply to all ages?
A: BMI interpretation differs for children and teens, using age- and sex-specific percentiles.

Q5: What's a good BMI for muscle gain?
