A **nanometre** (American spelling: **nanometer**, symbol **nm**) (Greek: νάνος, nanos, *dwarf*; μετρώ, metrό, *count*) is a unit of length in the metric system, equal to one billionth of a metre (or one millionth of a millimetre), which is the current SI base unit of length. It can be written in scientific notations as 1×10^{−9} m (engineering notation) or 1 E-9 m (exponential notation) — both meaning 1/1,000,000,000 metres. â€œSIâ€ redirects here. ...
