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 women who are 5 feet 5.7 inches (1.69 meters) tall, this calculator provides specific BMI calculation.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight_{kg} \) — Weight in kilograms
• \( height_{m} \) — Height in meters (5'5.7" = 1.69m)

Explanation: The formula divides your weight in kilograms by your height in meters squared. This gives a standardized measure of body weight relative to height.

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. For women of height 5'5.7", it helps assess if weight is in healthy range.

4. Using the Calculator

Tips: Enter your weight in kilograms. Height is pre-set to 1.69m (5 feet 5.7 inches) but can be adjusted if needed. All values must be valid (weight > 0, height > 0).

5. Frequently Asked Questions (FAQ)
