%N A322578 Decimal expansion of the Avogadro constant N_A in the 2019 SI system in units mol^(-1).
%C A322578 The Avogadro comstant N_A is one of the seven units of the 2019 SI system of units. See the BIMP link with the CGPM resolutions which become effective om May 20 2019. See also A322415.
%C A322578 This is also the conversion factor of the old SI unit mol into the reciprocal 2010 SI unit 1/N_A.
