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

US Navy method. Neck: just below the larynx. Men: abdomen at the level of the navel. Women: waist at its narrowest, and hips at the widest point of the buttocks. The equations were derived on these sites.
