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
120 µm – diameter of a human ovum
170 µm – length of the largest sperm cell in nature ^[1]^[2]
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^[3]
340 µm – length of a single pixel on a 17-inch monitor with a resolution of 1024×768
500 µm – typical length of Amoeba proteus, an amoeboid protist
500 µm – MEMS micro-engine^{[citation needed]}
560 µm - thickness of the central area of a human cornea^[4]
760 µm – thickness of a credit card
