# Amps to Kilowatts Converter

An amp to kW is an electrical energy converter. It helps you to convert amperes to kilowatts for direct current (DC), and alternate current (AC). You need to select the type of conversion you want AC or DC. Enter amperes value click on calculate to get an approximately equal value of AC or DC.

 Select current type: DC AC - Single phase AC - Three phase Enter current in amps (A): Enter voltage in volts (V):
 Power result in kilowatts (kW):

Ampere is a measuring unit of electric current. Ampere is representing as "A". A kilowatt is a unit of measurement for electrical energy. Watts are used to measuring small electrical energy and it is derived from watt. Kilowatts are units of measurement for high electrical energy. A kilowatt has 1,000 times the power of a watt. All modern equipment and gadgets are calibrated in kilowatts.

We know that power is equal to the voltage multiplied by current.

P = V x I

### To convert DC amps to kW conversion formula:

DC power is equal to the current I in amps multiplied by the voltage V in volts divided by 1000.

P (kW) = V x I / 1000

Where

P = Power is in kilowatts.

V = Voltage.

I = Current.

To convert single-phase, alternating current we use different formulas. Conversion of AC single-phase we need to use power factor.

AC single phase amps to kW conversion formula:

AC power is equal to the current I in amps multiplied by the voltage V in volts multiplied by power factor divided by 1000.

Power factor is the ratio between real powers to apparent power.

P (kW) = V x I x PF / 1000

Where

P = Power in kilowatts

V = Voltage.

I = Current.

PF = Power factor.

AC three-phase amps to kW conversion formula:

Ac three-phase amps to kW conversion formula are similar to AC single phase but power factor value is changed. Here in three-phase ac, we multiple power factors with √3.

P (kW) = √3 x PF x V x I / 1000

Where

P = Power in kilowatts

V = Voltage.

I = Current.

PF = Power factor.
