The accuracy of the procedure that converts the experimentally determined electron spectrum associated with fission of the nuclear fuels {sup 235}U, {sup 239}Pu, {sup 241}Pu, and {sup 238}U into the antineutrino {nu}{sub e} spectrum is examined. By using calculated sets of mutually consistent spectra, this work shows that the conversion procedure can result in a small {approx}1% error provided several conditions are met. Chief among them are the requirements that the average nuclear charge <Z> as a function of the {beta}-decay endpoint energy is independently known and that the {nu}{sub e} spectrum is binned into bins that are several times larger than the width of the slices used to fit the electron spectrum.
