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. It 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: BMI compares your weight to your height to estimate whether you're underweight, normal weight, overweight, or obese.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive screening method 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 weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0). For women, healthy BMI typically ranges from 18.5 to 24.9.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI for women?
A: For adult women, a BMI between 18.5 and 24.9 is generally considered healthy.

Q2: Does BMI differ for men and women?
A: The BMI calculation is the same, but healthy ranges may differ slightly due to body composition differences.

Q3: What are the limitations of BMI?
A: BMI doesn't distinguish between muscle and fat, so athletes may have high BMI without excess fat. It also doesn't account for fat distribution.

Q4: How often should I check my BMI?
A: Periodic checks (every 6-12 months) can help track changes, but dramatic changes should be discussed with a healthcare provider.

Q5: Is BMI accurate for all body types?
A: BMI may be less accurate for athletes, pregnant women, the elderly, and those with very muscular builds or very lean body types.
