Nanometre
Unit of length
The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm), or nanometer (American spelling), is a unit of length in the International System of Units (SI), equal to one billionth (short scale) or one thousand million (long scale) of a meter (0.000000001 m) and to 1000 picometres.
One nanometre can be expressed in scientific notation as 1 × 10−9 m and as 1/1000000000 m.

History
[edit]The nanometre was formerly known as the "millimicrometre" – or, more commonly, the "millimicron" for short – since it is 1/1000 of a micrometer. It was often denoted by the symbol mμ or, more rarely, as μμ (however, μμ should refer to a millionth of a micron).[1][2][3]
Etymology
[edit]The name combines the SI prefixnano- (from the Ancient Greekνάνος, nanos, "dwarf") with the parent unit name metre (from Greek μέτρον, metron, "unit of measurement").
