Comments

Inverse of A248508.

The value of Phi_0 is h / (2 * e) = 2.067833848... * 10^{-15} J s/C with joule J = kg m/s^2 and coulomb C = A s (A for ampere) based on SI definitions (effective on May 20, 2019). See the BIPM link with the CGPM resolutions which become effective on May 20 2019. See also A322415. - Ralf Steiner, Feb 14 2019

2010 CODATA value is 2.067833758(46) * 10^{-15} Wb; updated to 2.067833831(13) * 10^{-15} Wb in the 2014 correction.
