The human hair IS APRROX 0.004' (four thousands of an Inch and there are 12 inches to the foot)So therefore .004 divided by 12 is your answer.
Rating Newest Oldest. Best Answer: Human hair is about 70 micrometer thick. Diameters of atoms are 0.1-0.5 nm I will use diameter of carbon atom, since we are carbon-based life: Diamter of carbon atom is 0.22 nm Thus hair is 70 micrometers/ 0.22nm = 300,000 atoms thick.ating Newest Oldest.
