The Human Body
How many kilograms does the average adult's skin weigh, excluding the fat layer beneath it? (1 kg ≈ 2.2 lb)
Answer
4 kg
Skin is your body's largest organ, weighing about as much as a house cat. It's thickest on the soles of your feet and thinnest on your eyelids, where it's about as thin as a sheet of paper.
