This definition was endorsed at the 7th General Conference on Weights and Measures (CGPM) in 1927, [citation needed] but the material definition of the metre was retained until 1960. [21] From 1927 to 1960, the angstrom remained a secondary unit of length for use in spectroscopy, defined separately from the metre. [citation needed]
Nano (symbol n) is a unit prefix meaning one billionth.Used primarily with the metric system, this prefix denotes a factor of 10 −9 or 0.000 000 001.It is frequently encountered in science and electronics for prefixing units of time and length.

In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node.. The term "2 nanometer", or alternatively "20 angstrom" (a term used by Intel), has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors.
Nanotechnologies are based on physical processes which occur on a scale of nanometres (see nanoscopic scale). [1]The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.06 nm, and that of a ribosome is about 20 nm.
