Watts to Volts calculator

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

DC Watts to volts calculation




Volts: 0

V(V) = P(W) / I(A)

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

AC single phase watts to volts calculation





Volts: 0

V(V) = P(W) / (PF × I(A))

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

AC three phase watts to volts calculation





Volts: 0

VL-L(V) = P(W) / (√3 × PF × I(A))

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