How BMI is calculated

Body Mass Index (BMI) is calculated as weight in kilograms divided by height in metres squared (kg/m²). It's a quick screening tool to categorize weight ranges — underweight, normal, overweight, or obese — but it doesn't account for muscle mass, bone density, or body composition, so it's not a diagnosis on its own. Talk to a doctor for a full picture of your health.
