1. What is BMI?

BMI (Body Mass Index) is a simple index of weight-for-height that is commonly used to classify underweight, normal weight, overweight and obesity in adults. It is calculated by dividing weight in kilograms by the square of height in meters.

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 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 that may lead to health problems. For Canadian females, BMI is particularly useful for assessing risk of conditions like heart disease, high blood pressure, type 2 diabetes, gallstones, and certain cancers.

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. All values must be valid (weight > 0, height > 0).
