Kilowatts to Amps Calculator (kW to A) Full Load Current (FLA)

Kilowatts to amps Calculator (kW to A):

Using our kW to Amp calculator, you can convert DC, Single phase and three phase kilo Watts to Ampere Online. For that just fill the kW and Voltage value in the below two boxes and by pressing the calculating button to get the answer in Amps. For AC you need to enter power factor value too.

For Direct current:

Current in Amp (A) is equal to 1000 times of kW and divided by Voltage in Volts

I_(A) = 1000 × P_(kW) / V_(V)

In other words,

Amp = 1000 * kW / Volts.

For Single Phase:

As we said earlier, we need to fill the power factor also. AC current is the 1000 times of the real power and divided by the multiplication of voltage and power factor. Hence for calculating single-phase kW to Amp, the formula become,

I_(A) = 1000 × P_(kW) / (PF × V_(volts) )

Amp = 1000 * kW / pf * V_(Volts)

Here P_(kW) is a Real power,

For Three-phase:

Three-phase current I_(A) is equal to 1000 times of real power divided by the 3 times of multiplication of voltage between the line to neutral and power factor.

I_(A) = 1000 × P_(kW) / (3 × PF × V_L-N(V) )

While considering the line to line voltage, it will become

I_(A) = 1000 × P_(kW) / (√3 × PF × V_L-L(V) )

Let us take a simple example.

A Three-phase motor nameplate details are 5.5kW, 415 Volts Line to Line, and operated at 0.86 power factor. Calculate the current in Amps.

I_(A) = 1000 × 5.5 / (√3 × 0.86 × 440)

I_(A) = 5500/(1.732*415*0.86)

I_(A) = 8.9 Amps
