To help compare different orders of magnitude this page lists lengths between 10^-8 and 10^-7 m (10 nm and 100 nm).

• Distances shorter than 10 nm
• 20 nm — depth of bacterial flagellum
• 40 nm — extreme ultraviolet wavelength
• 90 nm — Human immunodeficiency virus (HIV) (Generally, viruses range in size from 20 nm to 450 nm.)
• <100 nm — 90% of the particles of wood smoke
• Distances longer than 100 nm
