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 micrometre is equal to
  • 1/10^th of a millimetre,
  • 0.00394 inches.
• 125 µm — length of a dust mite
• 200 µm — typical length of Paramecium caudatum, a ciliate protist
• 340 µm — approximate size of the dot at the end of this sentence. Also the 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 Amœba proteus, an amoeboid protist
• Distances longer than 1 mm
