By doing this at key locations, shown by research to be representative of the total amount of fat on the body, it is possible to estimate the total percent bodyfat of a person. This skinfold caliper has springs which exert a certain pressure on the skinfold, generally 10 gm./sq. mm., and an accurate scale which measures the thickness in millimeters."
