What are they, and what does the difference actually look like?
Two things. One honest scale.

A hair is a slender strand of protein that grows from the skin of humans and other mammals.
70 µmDiameterA sheet of paper is a flat material made from cellulose pulp, used for writing, printing or packaging.
100 µmThicknessThe thickness of Sheet of paper is about 1.43 times the diameter of 70 µm hair.
A 70 µm diameter example; hair thickness varies.
Defined examples — our methodology
The marked diameter is calibrated. Unmeasured illustration details are representative.
A 0.1 mm thick sheet. Paper stock and compression change thickness.
