1 myriometre

To help compare different orders of magnitude this page lists lengths between 10⁻⁴ m and 10⁻³ m (100 µm and 1 mm).

100 µm – 1/10 of a millimetre
100 µm – 0.00394 inches
100 µm – thickness of a coat of paint
100 µm – length of a dust particle
100–400 µm – length of Demodex mites living in human hair follicles
200 µm – typical length of Paramecium caudatum, a ciliate protist
250–300 µm – length of a dust mite^[1]
340 µm – length of a single pixel on a 17-inch monitor with a resolution of 1024×768
500 µm – diameter of a human ovum
500 µm – typical length of Amoeba proteus, an amoeboid protist
500 µm – MEMS micro-engine^{[citation needed]}
