Hair
70 µm - Diameter; example.
A hair is a slender strand of protein that grows from the skin of humans and other mammals.
A 70 µm diameter example; hair thickness varies.
Defined examples — our methodologyThe thickness of a sheet of paper is about 1.43 times the diameter of a hair. Selected basis: an example for Hair; an example for Sheet of paper; approximate values.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork.
