How to convert electric current in amps (A) to electric power in kilowatts (kW)?

amps to kilowatts calculation formula In Direct Current(DC)

P(kW) = I(in Amps) × V(in Volts) / 1000

So that you can define kilowatts(Kw) are equivalent to amps(A) times volts(V) divided by 1000

kilowatt = amps(A) × volt(V) / 1000
or
kW = A × V / 1000
Let’s take one example

Example#1
Find out the power utilization in kW where the current(I) is 5A and the voltage(V) supply is 120V
in the circuit.
Apply formula for the solution:
P = 5A × 120V / 1000 = 0.6kW

amps to kilowatts calculation formula in AC single phase

P(kW) = PF(Power Factor) × I(in Amps) × V(in Volts) / 1000

So that you can define kilowatts are equivalent to PF times amps(A) times volts(V) divided by 1000

kilowatt(Kw) = Power Factor × amps × volt / 1000
or
kW = PF × A × V / 1000
Let’s take one example

Example#2
Find out the power utilization in kW where the PF
is 0.8 and the phase current(I) is 5A and the RMS(Root Mean Square) voltage(V) supply is 120V in the circuit.
Apply formula for the solution:
P = 0.8 × 5A × 120V / 1000 = 0.48kW

amps to kilowatts calculation formula in AC three phase

P(in kW) = √3 × PF × I(in Amps) × VL-L(in Volts) / 1000

So that you can define kilowatts(Kw) are equivalent to √3 times  PF times amps(A) times volts(V) divided by 1000

kilowatt(Kw) = √3 × PF × amps(A) × volt(V) / 1000
or
kW = 1.732 × PF × A × V / 1000
Let’s take one example

Example#3
Find out the power utilization in kW when the PF is 0.8 and the phase current(I) is 5A and the
RMS(Root Mean Square) voltage(V) supply is 120V
Apply formula for the solution:
P = 1.732 × 0.8 × 5A × 120V / 1000 = 0.831kW
where DC = Direct Current, AC = Alternating Current
