1. What is BMI?

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults. It is defined as the weight in kilograms divided by the square of the height in meters (kg/m²).

2. How Does the Calculator Work?

The calculator uses the BMI formula:

Where:

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

Explanation: The calculator also determines your weight category and ideal weight range based on standard BMI classifications.

3. Importance of BMI Calculation

Details: 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.

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 adults, 18.5 to 24.9 is considered healthy. 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 (high muscle mass), pregnant women, children, and the elderly. Other measurements may be needed.

Q3: How often should I check my BMI?
A: For most adults, checking every 6-12 months is sufficient unless you're actively trying to change your weight.

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 children?
A: Children's BMI is interpreted differently using age and sex-specific percentile charts, not the adult categories.
