100 micrometres
Template:Orders of magnitude (length) imagemap human-scale 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 – average diameter of a strand of human hair[1]
- 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[2][3]
- 181 µm – maximum width of a strand of human hair[1]
- 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[4]
- 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[5]
- 760 µm – thickness of a credit card
