1 E-4 m

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^th 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 to 300 µm - length of a dust mite^[1]
• 340 µm - length of a single pixel on a 17" monitor with a resolution of 1024*768.
• 500 µm - MEMS micro-engine
• 500 µm - diameter of a human ovum
• 500 µm - typical length of Amoeba proteus, an amoeboid protist
