**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 V_{L} x P.F.)

Where V_{L} 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 V_{ph} x P.F.)

Where V_{ph} 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?

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.

Thank you, it was very good . . .
