1. What is BMI?

BMI (Body Mass Index) is a simple calculation using a person's height and weight to screen for weight categories that may lead to health problems. It's widely used in Australia as a general indicator of healthy weight.

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 provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems objectively with their patients.

3. Importance of BMI Calculation

Details: BMI is an important screening tool for weight categories in Australian women that may lead to health problems, but it's not diagnostic of body fatness or health. It's used to identify possible weight problems in adults.

4. Using the Calculator

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