1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. It's widely used in Queensland and globally as a screening tool to identify possible weight problems in adults.

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 formula divides your weight in kilograms by the square of your height in meters to calculate your BMI score.

3. Importance of BMI Calculation

Details: 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.

Tips: Enter your weight in kilograms and height in meters. For Queensland standards, measurements should be accurate for proper classification.
