2/28/2024 0 Comments Compare amp to volt conversion![]() ![]() Real power is the amount of actual power that can be drawn from a circuit. On the other hand, a watt (W) is a measurement of real power. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps. Current (Amps)Įquivalent Amps and Kilowatts at 240V AC Equivalent ampere and kilowatt values at 240 volts.Have you ever wondered why some power ratings are expressed in WATTS, some in AMPERES or AMPS, some in VOLTS, and some in KVA? This page will explain in simple terms the difference between the power ratings and describe when each should be used in your data center and network architecture planning.Ī KVA is simply 1,000 volt amps. You might also be interested in our amps to watts calculator.Įquivalent Amps and Kilowatts at 120V AC Equivalent ampere and kilowatt values at 120 volts. ![]() Thus, the power P in kilowatts is equal to the product of the square of the current I in amps and the resistance R in ohms, divided by 1,000. It is also possible to convert amps to kilowatts using circuit resistance with this formula: How to Convert Amps and Ohms to Kilowatts This formula gives you the power delivered by all three wires in a three-phase system, but when considering one wire, you will need to divide the result by three. Thus, the power P in kilowatts is equal to the product of the current I in amps, the line-to-neutral voltage V in volts, and the power factor PF, multiplied by 3, then divided by 1,000. The formula to convert amps to kilowatts for three-phase AC circuits where the line-to-neutral RMS voltage is known is: This equation gives you the power for one pair of wires in the three-phase system, but when considering all three pairs, you would need to multiply the result by three. Thus, the power P in kilowatts is equal to the product of the current I in amps, the line-to-line voltage V in volts, the power factor PF, and 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) = 12 A × 120 V / 1,000 P (kW) = 1,440 W / 1,000 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 power in kilowatts for a circuit with 12 amps of current at 120 volts.
