![]() Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts multiplied by the power factor PF multiplied by the square root of 3, divided by 1,000. The formula to convert amps to kilowatts for three-phase AC circuits where the current, line to line RMS voltage, and power factor is known is: Three-Phase AC Circuit Amps to Kilowatts Conversion Using Line to Line Voltage Try our power factor calculator to get the power factor if needed. Thus, the real power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts multiplied by the power factor PF, divided by 1,000. The PF is a property determined by the AC frequency and the amount of inductive or capacitive elements in the circuit. The magnitude of both real and reactive together is called the apparent power, and the PF gives the ratio of real power to apparent power. P (kW) = 1.44 kW Single-Phase AC Circuit Amps to Kilowatts ConversionĬonversion of amps to kilowatts for single-phase alternating current (AC) circuits using the current, RMS voltage, and power factor (PF) can be done with a slightly different formula.ĪC electrical power is composed of a real part, expressed in watts (W), and a reactive part, expressed in volt-amps (VA). ![]() ![]() ![]() For example, let’s find the kilowatts of power for a circuit with 12 amps of current at 120 volts. ![]()
