# Volts to Watts calculator

Enter the current in amps (A), voltage in volts (V), power factor (PF) from 0 to 1 with a 0.1 step (for AC), then press the Calculate button to get the result in kilowatts (kW).

## DC Volts to watts calculation

Current in amps (A)
Voltage in volts (V)

P(W) = I(A) x V(V)

The power P in watts (W) is equal to the phase current I in amps (A), multiplied by the voltage V in volts (V).

## AC single phase volts to watts calculation

Current in amps (A)
Voltage in volts (V)
Power factor (PF)

P(W) = PF × I(A) × V(V)

The power P in watts (W) is equal to the power factor PF, multiplied by the phase current I in amps (A), multiplied by the RMS voltage V in volts (V).

## AC three phase volts to watts calculation

Current in amps (A)
Voltage in volts (V)
Power factor (PF)

P(W) = √3 × PF × I(A) × VL-L(V)

The power P in watts (W) is equal to square root of 3, multiplied by the power factor PF, multiplied by the phase current I in amps (A), multiplied by the line to line RMS voltage VVL-L in volts (V).
