COMMENTS

e, the elementary charge, is exactly 1.602176634*10^(-19) coulomb according to the 2019 SI system definition (see A081823), whereas the value of h-bar, the reduced Planck constant (h/(2*Pi)), is given by A254181 and is equal to 1.054571817...*10^(-34) joule seconds (1.054571817...*10^(-34) kg*m^2*s^(-1)).

FORMULA

e/h-bar = e/(h/2*Pi) = (2*Pi*1.602176634*10^(-19))/(6.62607015*10^(-34)) A/J.

Equals A081823 / A254181.

EXAMPLE

e/h-bar = 1519267447878626.20125... A/J.
