This electrical online converter and calculator brings an easy way for you to change watts into amperes. You can make conversions for DC( direct current) as well as AC( alternating current). Moreover, you can also select different unit entities for putting in power and voltage in the respective boxes.

You can select a unit of power from milliwatt(mW), Watt(W), & kilowatt(kW), and any unit of voltage from volt(V), millivolt(mV) or kilovolt(kV). Now press the calculate button to get answers in ampere as well as milliampere.

Kilowatts (kW) to amps (A) calculator.

* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12

The current *I* in amps (A) is equal to 1000 times the power *P* in kilowatts (kW), divided by the voltage *V* in volts (V):

* I*_{(A)} = 1000 ×* P*_{(kW)} / * V*_{(V)}

The phase current *I* in amps (A) is equal to 1000 times the power *P* in kilowatts (kW), divided by the power factor *PF* times the RMS voltage *V* in volts (V):

* I*_{(A)} = 1000 ×* P*_{(kW)} / (*PF* × * V*_{(V)} )

The phase current *I* in amps (A) is equal to 1000 times the power *P* in kilowatts (kW), divided by square root of 3 times the power factor *PF* times the line to line RMS voltage *V*_{L-L} in volts (V):

* I*_{(A)} = 1000 ×* P*_{(kW)} / (*√*3 × * PF* × * V*_{L-L(V)} )

The phase current *I* in amps (A) is equal to 1000 times the power *P* in kilowatts (kW), divided by 3 times the power factor *PF* times the line to neutral RMS voltage *V*_{L-N} in volts (V):

* I*_{(A)} = 1000 ×* P*_{(kW)} / (3 × * PF* × * V*_{L-N(V)} )

Do not use typical power factor values for accurate calculations.

Device | Typical power factor |
---|---|

Resistive load | 1 |

Fluorescent lamp | 0.95 |

Incandescent lamp | 1 |

Induction motor full load | 0.85 |

Induction motor no load | 0.35 |

Resistive oven | 1 |

Synchronous motor | 0.9 |

This calculator allows the users to calculate/convert watts and volts into amperes as well as amperes into watts and volts. You can select the current type from DC, AC single-phase and AC 3-phase. You can also different denominations for writing in voltage and power. The available unit denominations for power include mW, W, & kW and for voltage mV, V, & kV. The answer is given in two denominations i.e amperes and milliamperes.

You can also use the swap button here for reverse conversions i.e from milliampere & amperes to watts and volts.

Divide the wattage by 1000 to get the watts: 1500 watts 1000 is 1.5 kW.

Multiply the kilowatts multiplied by the amount of time used: 1.5 kW X 2 hours = 3 kWh each day.

Calculate the total energy consumption for the months (30 days) 3 kWh divided by 30 days equals 90 kWh for a month.
