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. BMI provides a reliable indicator of body fatness for most people.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

Explanation: The formula divides your weight by the square of your height to give a number that correlates with body fat percentage.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive screening tool for weight categories that may lead to health problems. It's used to identify possible weight problems in adults.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range?
A: For most adults, an ideal BMI is between 18.5 and 24.9. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

Q2: Does BMI apply to everyone?
A: BMI may not be accurate for athletes (who have more muscle), pregnant women, children, and the elderly.

Q3: How can I improve my BMI?
A: For overweight individuals, losing 5-10% of body weight can significantly improve health. Combine healthy eating with regular exercise.

Q4: What are the limitations of BMI?
A: BMI doesn't distinguish between muscle and fat, and doesn't account for fat distribution, which affects health risks.

Q5: Should I use BMI for weight loss goals?
A: BMI is a good screening tool, but body fat percentage and waist circumference may provide more specific health information.
