1 E-8 m.html



To help compare different orders of magnitude this page lists lengths between 10⁻⁸ and 10⁻⁷ metres (10 nanometres and 100 nanometres).

Distances shorter than 10 nanometres

• 10 nm = 10 nanometres = 10⁻⁸ metres
• 20 nm — width of bacterial flagellum
• 40 nm — width of tobacco mosaic virus
• 40 nm — extreme ultraviolet wavelength
• 45 nm — size of the smallest transistors in a microprocessor produced in 2007.
• 90 nm — Human immunodeficiency virus (HIV) (Generally, viruses range in size from 20 nm to 450 nm.)
• 100 nm — larger than 90% of the particles of wood smoke^{citation needed}

Distances longer than 100 nanometres
