Comments

Since eV := 1.602176634*10^(-19) J (see A081823), h-bar := (6.62607015*10^(-34))/(2*Pi) J*s (see A003676 and A254181), and c := 299792458 m/s (see A003678), it follows that h-bar*c/eV = ((6.62607015*10^(-34)*299792458)/(2*Pi))/(1.602176634*10^(-19)) meters. Thus, m = 10^7/1.973269804593... h-bar*c/eV.
