Weighted oscillator strengths, weighted radiative rates, and line strengths for all the E1 transitions between 285 fine-structure levels belonging to the 3d{sup 6}, 3d{sup 5}4s, and 3d{sup 5}4p configurations of Fe III are presented, in ascending order of wavelength. Calculations have been undertaken using the general configuration interaction (CI) code CIV3. The large configuration set is constructed by allowing single and double replacements from any of 3d{sup 6}, 3d{sup 5}4s, 3d{sup 5}4p, and 3d{sup 5}4d configurations to nl orbitals with n{<=}5,l{<=}3 as well as 6p. Additional selective promotions from 3s and 3p subshells are also included in the CI expansions to incorporate the important correlation effects in the n=3 shell. Results of some strong transitions between levels of 3d{sup 6}, 3d{sup 5}4s, and 3d{sup 5}4p configurations are also presented and compared with other available calculations. It is found that large disagreements occur in many transitions among the existing calculations.
