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

• Distances shorter than 10 µm
• 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^th inch, commonly referred to as 1 mil in the US and 1 thou in the UK
• 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)
• Distances longer than 100 µm
