10 nanometres

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

Distances shorter than 10 nm Distances longer than 100 nm
 * 20 nm &mdash; width of bacterial flagellum
 * 40 nm &mdash; width of tobacco mosaic virus
 * 40 nm &mdash; extreme ultraviolet wavelength
 * 45 nm &mdash; size of the smallest transistors in a microprocessor produced in 2007.
 * 90 nm &mdash; Human immunodeficiency virus (HIV) (Generally, viruses range in size from 20 nm to 450 nm.)
 * <100 nm &mdash; 90% of the particles of wood smoke
