I built my spreadsheet based off the calculator below. It gives a good overview of how exactly to reverse engineer that fan power. Careful when switching between units.

UPDATE: Not that this is really relevant to the original question (more so at the title of the question), but for any of those looking on how to complete the calculation for compliance modeling, GBCI's Table 1.4 spreadsheet >link< to track your inputs is a great tool to deconstruct for really understanding to how to model according to Appendix G of ASHRAE 90.1. Un-hide all the mechanical fan tabs and swim through all the references.
