How much does a human arm weigh?

Answer 1

The total arm mass is given as mean 3.216kg with a standard deviation of 0.464kg

in Clauser, "Weigth, volume, and center of mass of segments of the human body", 1969, p.45

(http://www.ulb.ac.be/medecine/anatemb/biblio/Clauser1969.pdf):

More details in Chandler, "Investigation of Inertial Properties of the Human Body", 1975, p.72-79

(http://www.ulb.ac.be/medecine/anatemb/biblio/Chandler1975.pdf)

come the following data:

Upper arm (right): mean 1.843kg s.d. 0.218kg.

Upper arm (left): mean 1.888kg s.d. 0.299 kg.

Forearm (right): mean 1.113kg, s.d. 0.271kg.

Forearm (left): mean 1.088kg s.d. 0.185kg

Hand (right): mean 0.400kg s.d. 0.091kg

Hand (left): mean 0.374kg s.d. 0.062kg

That gives a total mean arm mass of 3.35kg (for right and left).

Approximately 5 to 6 percent.
