How this tool works
BMI equals weight in kilograms divided by height in meters squared. Adult category wording follows CDC guidance; BMI is a screening measure, not a diagnosis.
Limits to know
BMI is an adult screening ratio, not a diagnosis, and does not directly measure body fat or distinguish fat from muscle. Pregnancy, age, ethnicity, disability, and individual health context require appropriate clinical interpretation.
