How to convert electric current in amps (A) to electric power in kilowatts (kW).
You can calculate kilowatts from amps and volts. You can't convert amps to kilowatts since kilowatts and amps units do not measure the same quantity.
The power P in kilowatts is equal to the current I in amps, times the voltage V in volts divided by 1000:
P(kW) = I(A) × V(V) / 1000
So kilowatts are equal to amps times volts divided by 1000:
kilowatt = amp × volt / 1000
or
kW = A × V / 1000
What is power consumption in kW when the current is 3A and the voltage supply is 130V?
Answer: the power P is equal to current of 3 amps times the voltage of 130 volts, divided by 1000.
P = 3A × 130V / 1000 = 0.39kW
What is power consumption in kW when the current is 3A and the voltage supply is 190V?
Answer: the power P is equal to current of 3 amps times the voltage of 190 volts, divided by 1000.
P = 3A × 190V / 1000 = 0.57kW
What is power consumption in kW when the current is 8A and the voltage supply is 230V?
Answer: the power P is equal to current of 8 amps times the voltage of 230 volts, divided by 1000.
P = 8A × 230V / 1000 = 1.84kW
The real power P in kilowatts is equal to the power factor PF times the phase current I in amps, times the RMS voltage V in volts divided by 1000:
P(kW) = PF × I(A) × V(V) / 1000
So kilowatts are equal to power factor times amps times volts divided by 1000:
kilowatt = PF × amp × volt / 1000
or
kW = PF × A × V / 1000
What is power consumption in kW when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 130V?
Answer: the power P is equal to power factor of 0.8 times current of 3 amps times voltage of 130 volts, divided by 1000.
P = 0.8 × 3A × 130V / 1000 = 0.312kW
What is power consumption in kW when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 190V?
Answer: the power P is equal to power factor of 0.8 times current of 3 amps times voltage of 190 volts, divided by 1000.
P = 0.8 × 3A × 190V / 1000 = 0.456kW
What is power consumption in kW when the power factor is 0.8 and the phase current is 8A and the RMS voltage supply is 230V?
Answer: the power P is equal to power factor of 0.8 times current of 8 amps times voltage of 230 volts, divided by 1000.
P = 0.8 × 8A × 130V / 1000 = 1.472kW
The real power P in kilowatts is equal to square root of 3 times the power factor PF times the phase current I in amps, times the line to line RMS voltage VL-L in volts divided by 1000:
P(kW) = √3 × PF × I(A) × VL-L(V) / 1000
So kilowatts are equal to square root of 3 times power factor PF times amps times volts divided by 1000:
kilowatt = √3 × PF × amp × volt / 1000
or
kW = √3 × PF × A × V / 1000
What is power consumption in kW when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 130V?
Answer: the power P is equal to square root of 3 times power factor of 0.8 times current of 3 amps times the voltage of 130 volts, divided by 1000.
P = √3 × 0.8 × 3A × 130V / 1000 = 0.312kW
What is power consumption in kW when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 190V?
Answer: the power P is equal to square root of 3 times power factor of 0.8 times current of 3 amps times the voltage of 190 volts, divided by 1000.
P = √3 × 0.8 × 3A × 190V / 1000 = 0.456kW
What is power consumption in kW when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 230V?
Answer: the power P is equal to square root of 8 times power factor of 0.8 times current of 8 amps times the voltage of 230 volts, divided by 1000.
P = √3 × 0.8 × 8A × 230V / 1000 = 1.472
How to convert kilowatts to amps ►
1. P(KW) = √3 × PF × I(A) × VL-L(V) / 1000.
2. kW = √3 × pF × amp × volt / 1000.
3. kW = √3 × pF × A × V / 1000.
4. P = √3 × 0.8 × 3A × 110V / 1000 = 0.457kW.

We divide the power in watts P(W) by 1,000 to get the power in kilowatts P(kW). Here's the formula to convert watts to kilowatts: P(kW) = P(W) / 1,000.
Here's how many amperes it takes: A 1 kW washing machine requires about 4.55 amperes to run.
