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. For females, the normal range is typically 18.5–24.9.

2. How Does the Calculator Work?

The calculator uses the BMI formula:

Where:

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

Explanation: 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.

3. Importance of BMI Calculation

Details: BMI is a screening tool to identify possible weight problems in adults. For females, maintaining a BMI in the normal range (18.5–24.9) is associated with lower risks of weight-related health problems.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For accuracy, measure height without shoes and weight in light clothing. All values must be valid (weight > 0, height > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range for adult females?
A: For adult females, a BMI between 18.5 and 24.9 is generally considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

Q2: Does BMI differ for males and females?
A: The same BMI categories apply to both adult males and females, though body composition differs between genders at the same BMI.

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

Q4: Is BMI accurate for all body types?
A: BMI may be less accurate for athletes (who have more muscle), pregnant women, and the elderly (who may have lost muscle mass).

Q5: Should BMI be the only measure of healthy weight?
A: No. Waist circumference, body fat percentage, and other measurements should also be considered for a complete health assessment.
