Single-phase hp = E x I x Percent Efficiency x PF/746
1/8th of a horsepower ....I think....:::::scratching head:::::..
The formula given above is used to determine the actual operating horsepower of any single-phase motor. If a motor such as a compressor motor does not state the motor horsepower, then this formula will also work to determine the rated or actual operating horsepower.
If the motor name/data plate information such as the rated voltage, rated FLA, rated efficiency, and listed power factor are placed in the formula, the resulting answer will be the rated horsepower.
The common use for this calculation is to determine the actual operating horsepower for a motor as it is presently being used.

A 115 volt single phase motor drawing 4.3 amps is approximately 1/6 HP from motor charts - http://www.elec-toolbox.com/usefulinfo/flamtrcharts.htm
