WebSep 19, 2024 · How to Calculate Fan Efficiency. The efficiency of a fan as an energy converter is determined by the ratio of its output to the input power: \eta =\frac {P_ {out}} {P_ {in}} Input power delivered to a fan is: P_ {in}=V\times I. V and I are the electrical voltage (in Volts) and amperage (in Amps). P is measured in Watts.
