BMI

Body Mass Index

For education. Check every result.

Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.

Fill in every field above, then select Calculate.

How it is calculated

BMI = weight(kg) / height(m)². Does not account for muscle mass, age, or body composition.

About

Weight relative to height, used to categorise underweight to obesity. It cannot tell muscle from fat, so it misclassifies athletes and the elderly.
