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 fibre¹
• 10 µm — transistor width of the Intel 4004, the world's first commercial microprocessor
• 5-20 µm — dust mite excreta²
• 10.6 µm — wavelength of light emitted by a carbon dioxide laser
• 13 µm - width of nylon fibre^{citation needed}
• 14 µm - width of polyester fibre^{citation needed}
• 15 µm — width of silk fibre
• 16 µm — diameter of a micromirror in a typical Digital micromirror device
• 17 µm — length of a tobacco mosaic virus
• 17.6 µm — one twip, a unit of length in typography
• 10 to 55 µm — width of wool fibre¹
• 25.4 µm — 1/1000^th inch, commonly referred to as 1 mil in the U.S. 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
• 50 µm — typical length of a human liver cell, an average-sized body cell
• 80 µm — average width of human hair (ranges from 18 to 180 µm)
• 91 µm — the size of the Earth if the Sun is scaled to the size of a marble (1cm).
