Amps to kW calculator

How This Free Tool Converts Values

This is a minimalist tool to convert units of Amperes into KiloWatts by simply hitting convert after entering the number of Amp units you want to convert to KiloWatt. This converter can be used to measure and count the energy consumption in homes or businesses to make a better assessment.

DC AMPs to kWatts

While using this tool the power 'P' in kilowatts (kW) is equal to the current 'I' in amps (A), times the voltage V in volts (V) divided by 1000. This gives you the accurate results.

Formula: P(kW) = I(A) × V(V) / 1000

AC Single Phase AMPs to kWatts

The power P in kilowatts (kW) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V) divided by 1000.

Formula: P(kW) = PF × I(A) × V(V) / 1000

AC 3 Phase AMPs to kWatts

Calculation is done with line to line voltage. The power P in kilowatts (kW) is equal to square root of 3 times the power factor PF times the phase current I in amps (A), times the line to line RMS voltage VL-L in volts (V) divided by 1000:

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

For the calculation of line to neutral voltage, the power P in kilowatts (kW) is equal to 3 times the power factor PF times the phase current I in amps (A), times the line to neutral RMS voltage VL-N in volts (V) divided by 1000:

Line to Neutral Formula: P(kW) = 3 × PF × I(A) × VL-N(V) / 1000
