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 and is 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 divides a person's weight by the square of their height to categorize their weight status.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive, and noninvasive method to assess weight status. For most people, BMI correlates with body fatness. The categories are:

• Underweight: BMI less than 18.5
• Normal weight: BMI 18.5 to 24.9
• Overweight: BMI 25 to 29.9
• Obese: BMI 30 or greater

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For women, BMI interpretation is the same as for men, though body fat percentage may differ at the same BMI.

5. Frequently Asked Questions (FAQ)

Q1: Is BMI different for women and men?
A: The calculation is the same, but women typically have more body fat than men at the same BMI.

Q2: What is a healthy BMI range for women?
A: 18.5 to 24.9 is considered healthy, though individual factors like muscle mass should be considered.

Q3: Are there limitations to BMI?
A: BMI doesn't distinguish between muscle and fat, so muscular individuals may have high BMI without excess fat.

Q4: How often should I check my BMI?
A: Periodic checks (every few months) can help track changes, but don't overemphasize small fluctuations.

Q5: Should pregnant women use BMI?
A: Standard BMI categories don't apply during pregnancy. Consult your healthcare provider for guidance.
