1 E-5 m

To help compare different orders of magnitude this page lists lengths between 10 micrometre and 100 micrometre (10^-5 m and 10^-4 m). See also lengths of other orders of magnitude.

• Shorter lengths
• 10 µm -- Width of cotton fibre
• 10.6 µm -- wavelength of light emitted by a carbon dioxide laser
• 12 µm -- Width of acrylic fibre
• 13 µm -- Width of nylon fibre
• 14 µm -- Width of polyester fibre
• 15 µm -- Width of silk fibre
• 17 µm -- Dust mite excreta ¹
• 20 µm -- Width of wool fibre
• 25.4 µm -- 1/1000 inch, commonly referred to as 1 mil
• 30-50 µm -- diameter of a minicolumn in the human cortex
• 50 µm -- typical length of Euglena gracilis, a flagellate protist
• 80 µm -- average width of human hair (ranges from 18 to 180 µm)
• Longer lengths
