Kilowatt to Ampere | kW to Amps Converter

Kilowatts and ampere are the units of two different parameters of electricity. While the former quantifies the amount of power consumed by a load at any instant the latter quantifies the amount of current drawn by the load. You can use the following calculator to convert kilowatt to ampere (kw to amps). Enter the kW, voltage, type of voltage and power factor for calculation.

How to convert kilowatts to ampere?

Since kilowatt (kW) is a measure of power and Ampere (amp or A) is the measure of current, kW cannot be directly converted into ampere or vice versa. Below are the formulae used to convert kilowatts to amperes (kW to amps).

One kilowatt = 1000 watts

DC – kilowatts (kW) to ampere (amps)

For any DC circuit, Current, I = 1000 x kW / Vdc

Where Vdc is the applied DC voltage.

Therefore, amps can be calculated from DC – kW by dividing kilowatt by voltage and multiplying it by 1000.

Single Phase AC – kW to amps

For any single-phase AC circuit, Current, I = 1000 x kW / (Vac x P.F.)

Where Vac is the RMS value of the applied AC voltage and P.F. is the power factor of the load

Therefore, amps can be calculated from AC – kW by dividing kW by the product of the RMS value of applied AC voltage and power factor and multiplying it by 1000.

Three Phase AC – kW to amps

For a three-phase AC circuit, if the line to line voltage is known, ampere can be calculated from kW using the following formula.

For any three-phase AC circuit, Current, I = 1000 x kW / (√3 x VL x P.F.)

Where VL is the RMS value of the applied line voltage and P.F. is the power factor of the load

Therefore, amps can be calculated from AC – kW by dividing kW by √3 times the product of the RMS value of applied line voltage, power factor and multiplying it by 1000.

For a three-phase AC circuit, if the phase voltage is known, ampere can be calculated from kW using the following formula.

For any three-phase AC circuit, Current, I = 1000 x kW / (3 x Vph x P.F.)

Where Vph is the RMS value of the applied phase voltage and P.F. is the power factor of the load

Therefore, amps can be calculated from AC – kW by dividing kW by 3 times the product of the RMS value of applied phase voltage, power factor and multiplying it by 1000.

    I have a fridge with 125kw how to find the amps?

    1. admin

      You can calculate the current drained by your fridge as below:

      If your fridge is three-phase
      Current in Amps = 125kW / (1.732 * Phase voltage *0.95)
      Where 0.85 is assumed power factor. You can replace it with the actual power factor.
