Lately, employees at my service center have been challenged by the conversion of kW to hp for estimates and quotes. To help employees, I posted the following in the service center: The conversion formula for kW to hp is arrived at by multiplying the kW x (1.341) = hp (1/1.341 = 0.746; to convert hp to kW, multiply hp times 0.746 = kW). (Example: 15 x 1.341 = 20.115) This post allows my employees to easily cross-reference to our pricing charts
Another similar experience is when we have discussed RPMs vs. frequency. Utilizing RPM = (120 x Hz)/poles OR poles = (120 x Hz)/RPM. (Example: (120 x 50 Hz)/1500 RPM = 4 poles).
