== Nanometre ==

A '''Nanometre''' ({{IPA|nænəˌmiːtər}}) is a unit of length in the [[International System of Units (SI)|SI]] equal to one billionth (short scale) of a metre ({{convert|1E-9|m|in|lk=on}}). The term combines the [[Greek language|Greek]] words ''nano'' meaning "dwarf" and ''metron'' meaning "measure". 

== Etymology ==

The term ''nanometre'' originates from the [[Greek language|Greek]] words ''nano'' which means "dwarf" and ''metron'' which means "measure". The prefix ''nano-'' is used in the [[International System of Units (SI)|SI]] to denote a factor of 10<sup>-9</sup> or 0.000000001.
