To help compare different orders of magnitude, this page lists lengths between 10−4 m and 10−3 m (100 µm and 1 mm). Distances shorter than 100 µm * 100 µm – 1/10 of a millimetre * 100 µm – 0.00394 inches * 100 µm – average diameter of a strand of human hair〔According to ''The Physics Factbook'', the diameter of human hair ranges from 17 to 181 µm. 〕 * 100 µm – thickness of a coat of paint * 100 µm – length of a dust particle * 110 µm – half way between the Planck scale and the diameter of the Observable universe, √(8.8×1026meters/1.6×10−35meters) × 1.6×10−35meters=110 µm * 120 µm – diameter of a human ovum * 170 µm – length of the largest sperm cell in nature〔http://www2.oakland.edu/biology/lindemann/spermfacts.htm〕〔http://www.neatorama.com/2006/06/17/worlds-biggest-sperm-belongs-to-a-tiny-fly/〕 * 181 µm – maximum width of a strand of human hair〔 * 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〔(House Dust Mites HYG-2157-97 ). Retrieved 2008-12-04〕 * 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 * * 560 µm - thickness of the central area of a human cornea * 760 µm – thickness of an identification card Distances longer than 1 mm ==Notes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「100 micrometres」の詳細全文を読む スポンサード リンク
