Editing Nanometre (section)

==History==
The nanometre was formerly known as the "''millimicrometre''"&nbsp;– or, more commonly, the "''millimicron''" for short&nbsp;– since it is {{sfrac|1000}} of a [[micrometre|micrometer]]. It was often denoted by the symbol ''mμ'' or, more rarely, as ''μμ'' (however, ''μμ'' should refer to a ''millionth'' of a micron).<ref name=":0">{{Cite journal |first1=The |last1=Svedberg |first2=J.
