Watts (W) to volts (V) calculator.

Enter the power in watts,
current in amps and press the *
Calculate* button to get the voltage in volts:

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

*V*_{(V)} = *P*_{(W)}* */* I*_{(A)}

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

*V*_{(V)} = * P*_{(W)} / (*PF* × * I*_{(A)}* *
)

The line to line RMS voltage *V*_{L-L} in volts (V) is equal to the power
*P* in watts (W), divided by square root of 3 times the
power factor *PF* times the
phase current *I* in amps (A):

*V*_{L-L(V)} = * P*_{(W)} / (*√*3
× * PF* × * I*_{(A)}* *) ≈ * P*_{(W)} / (1.732
× * PF* × * I*_{(A)}* *)

The line to neutral RMS voltage *V*_{L-N} in volts (V) is equal to the power
*P* in watts (W), divided by 3 times the
power factor *PF* times the phase current *I* in amps (A):

*V*_{L-N(V)} = * P*_{(W)} / (3 × * PF* × * I*_{(A)}* *)
