The volt (V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. P(kW) 3 × PF × VL-L(V) This formula relates the phase current I (in amps) to the power P (in kilowatts), power factor PF, and line to line RMS voltage VL-L (in volts). The ampere (A or amp) is the base unit of electric current in the International System of Units (SI). In the International System of Units (SI) it is defined as a derived unit of 1/1000 joule per second, and is used to quantify the rate of energy transfer. For AC circuits with inductive or capacitive reactance use other calculator.ġ) Power = Electric potential * Electric currentĢ) Electric current = Power / Electric potentialģ) Electric potential = Power / Electric current Type in your own numbers in the form to convert the units.
#Kw to amp conversion how to
Use this calculators to learn how to convert between kilowatts and amperes. This is a simple program for converting kw to amps. The higher the wattage is, the more power and output. With this online calculator, you can convert amperes to kilowatts. Amps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. Theory and formulas for conversion - see bottom on this page. I = 1000 × 0.44kW / ( √3 × 0.9 × 110V) = 2.With this online calculator you can convert Amps to kW and vice versa. Given that the power factor is 0.9, the power consumption is 0.44 kilowatts, and the voltage supply is 110V, calculate the phase current in amperes. In this case, the phase current I in amperes (A), is calculated by multiplying the real power P, in kilo-watts (kW) by 1000 and then dividing the result by the power factor multiplied by the square root of three times the line in line RMS V L- L voltage, in volts (V).Ĭurrent I in amperes (A) = 1000 multiplied by kW divided by the PF times the root of 3 times the voltsĪmps = 1000 × kilowatts / ( √3 × PF × volts) I = 1000 × 0.44kW / (0.7 × 110V) = 5.71A AC three phase kilowatts to amps calculation Work out the phase current, in amperes, given that the power factor in a circuit is 0.7, the power consumption is 0.44 kilowatts and the RMS voltage is 110V.
In this case, the current I in amps (A) is calculated by multiplying the real power P, in kW by 1000 and then dividing the result by the power factor PF multiplied by the RMS voltage V, in volts (V).Ĭurrent I in amps= power P in kW times 1000/ Volts times the power factor 18246 NaK - NITROGEN LIQUID METAL MHD CONVERTER TESTS AT 30 kW.
I = 1000 × 0.44kW / 110V = 4A AC single phase kilowatts to amps calculation Energy Conversion Refer also to abstracts 19409, 19883, 20407, 20421, and 20443. Given that the power consumption by an electrical appliance is 0.44 kilowatts and that the voltage across it terminals is 110V, calculate the current in amps through the appliance. To calculate the current I in amps (A), you should multiply the real power P, in kilowatts by 1000 and divide the result by the voltage V, in volts (V).Ĭurrent in amps (A) = kilowatts multiplied by 1000 Since amps and kilowatts are sued to measure the same quantity, it is possible to work out the amps given the volts and kilowatts. DC kW to Amps It is a ratio of 1000 times kW to the system voltages. Enter the known kW and system voltages to find the current through the circuit. How to convert electric power in kilowatts (kW) to electric current in amps (A) kW to Amps conversion calculator is used to calculate amperes from the known power kilowatts in DC, Single, two, or three phase AC circuits.
