"What if" questions are often asked regarding reliability figures of merit. The tool provides a quick "back-of-the-envelope" estimate based on conversion factors found on
page 105 - 107 of the USAF Rome Laboratory Reliability Engineer's Toolkit (Ref. 1), with this correction. The underlying conversion factors were developed from MIL-HDBK-217F relationships.
Enter the current reliability value and then select one or more of the conversion options (environment, temperature or part quality) by setting the "From" and "To" pull-down selections.
