Measurement of fat thickness in man: a comparison of ultrasound, Harpenden calipers and electrical conductivity

1. Subcutaneous fat thickness has been measured by three different techniques in forty-one subjects. 2. Ultrasound provided the most accurate measurement in experienced hands. 3. A method based on electrical conductivity was also accurate but was unpleasant for the subject. 4. Harpenden calipers were the least satisfactory of the three techniques tested.
