1 nanometre

To help compare different orders of magnitudes this page lists lengths between 10&minus;9 m (meter) and 10&minus;8 m (1 nm and 10 nm).

Distances shorter than 1 nm Distances longer than 10 nm
 * 1 nm = 1 nanometer = 1000 picometers = 10 Ångströms
 * 1 nm &mdash; rough length of a sucrose molecule, as calculated by Albert Einstein
 * 1.1 nm &mdash; diameter of a single-walled carbon nanotube
 * 2 nm &mdash; diameter of DNA helix
 * 3 nm &mdash; flying height of the head of a hard disk
 * 6.8 nm &mdash; width of a hemoglobin molecule
