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: The equation divides your weight by the square of your height to estimate body fat percentage.

3. Importance of BMI Calculation

Details: BMI screening helps identify potential weight problems in adults. However, it's not a diagnostic tool - it doesn't directly assess body fat. Healthcare providers need further assessments for diagnosis.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range for women?
A: For most women, a BMI between 18.5 and 24.9 is considered healthy. However, body composition varies.

Q2: Does BMI differ for men and women?
A: The calculation is the same, but women typically have more body fat than men at the same BMI.

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.

Q4: Is BMI accurate for pregnant women?
A: No, BMI calculations during pregnancy aren't meaningful due to weight changes.

Q5: What's better than BMI for body fat measurement?
A: Methods like skinfold thickness measurements, DEXA scans, or hydrostatic weighing are more accurate.
