Understanding the BMI Calculator
What is BMI?
Body Mass Index (BMI) is a measure that uses your height and weight to work out if your weight is healthy. It's a widely used screening tool to identify potential weight problems for adults.
How to Calculate Your BMI
Select your preferred units (Metric or Imperial). Enter your height in centimeters or inches, and your weight in kilograms or pounds. The calculator will instantly display your BMI and the corresponding weight category.
BMI Categories Explained
BMI is categorized into several groups: Underweight, Normal weight, Overweight, and Obesity. These categories help assess where your BMI falls on the spectrum and can be an indicator of potential health issues.
Why Check Your BMI?
Checking your BMI can help you and your healthcare provider assess your health status and potential risks. While not a diagnostic tool, it's a good starting point for conversations about weight and health.
