How this tool works
BMI is weight in kilograms divided by height in metres squared. It does not measure body fat or distinguish muscle from fat. For adults aged 20–100. These are educational estimates, not diagnoses, treatment targets or medication-dosing guidance. They are not designed for children, pregnancy or breastfeeding; body composition and health conditions can make the estimates unsuitable. Discuss personal concerns with a qualified clinician.
