The conversion assumes the infinite nuclear-mass approximation ideal for hydrogen-like atoms only.
-
It may not accurately reflect energies involving multi-electron atoms or nuclear mass corrections.
-
Conversion precision is subject to the exactness of fundamental constant values and measurement uncertainties.
-
Not intended for energy scales outside atomic and particle physics contexts.
