How to Calculate Kilowatts to Amps

AC, DC Kilowatts to Amps manual calculation

kW (DC) to Amps formula:

I(A) = 1000 × P(kW) / V(V)

current I in amps (A) is equal to 1000 multiplied by (P) power in kW, divided by the voltage V in volts.

kW (AC single phase) to Amps formula:

I(A) = 1000 × P(kW) / (PF × V(V) )

kW (AC three phase) to Amps formula:
Line to line voltage

I(A) = 1000 × P(kW) / (√3 × PF × VL-L(V) )

Line to neutral voltage

I(A) = 1000 × P(kW) / (3 × PF × VL-N(V) )

(PF) Power Factor values:

Device Typical power factor
Resistive load 1
Fluorescent lamp 0.95
Incandescent lamp 1
Induction motor full load 0.85
Induction motor no load 0.35
Resistive oven 1
Synchronous motor 0.9

*For accurate calculations do not use typical power factor values.
