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)).
