What is the average weight of one human leg?  This could be absolute or in relative to body mass or any other available form you have these data in.  Thank you.

Each leg is about 10% of the total body weight, so for an adult male the answer is aproximately 7Kg. Each arm is about 6% of the total body weight and the head is 8-9%. Thus the main thorax and abdomen (including spine and pelvic bones) constitutes about 60% of the total.
