Power Factor = Watts / (Volts x Amperes) Three Phase Kilowatts = (Volts x Amperes x Power Factor x 1.732) / 1000 Three Phase Volt-Amperes = Volts x Amperes x 1.732 Three Phase Amperes = (746 x Horsepower) / (1.732 x Volts x Efficiency x Power Factor) Single Phase Kilowatts = (Volts x Amperes x Power Factor) / 1000 Single Phase Amperes = (746 x Horsepower) / (Volts x Efficiency x Power Factor)
