Understanding the BMI Calculator
What is BMI?
Body Mass Index (BMI) is a measure that uses height and weight to determine if your weight is healthy. It's a widely used screening tool to identify potential weight problems in adults.
How to Calculate BMI
Choose your preferred unit system (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 corresponding weight category.
BMI Category Breakdown
BMI is divided into several groups: underweight, normal weight, overweight, and obesity. These categories help assess where your BMI falls on the spectrum and can be indicators 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 it's not a diagnostic tool, it's a good starting point for conversations about weight and health.
