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, 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.
picometre <<< nanometre <<< micrometre <<< millimetre < centimetre < decimetre < metre < decametre < hectometre < kilometre
It is one of the more often used units for very small lengths, and equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of Nanotechnology.
It is also the most common unit used to describe the manufacturing technology used in the semiconductor industry.
'Nanometry' is the science of counting and measuring particles on the scale of nanometres.
