## Watts to volts calculator

Watts (W) to volts (V) calculator.

Enter the power in watts, current in amps and press the

Calculatebutton to get the voltage in volts:## DC watts to volts calculation

The voltage

Vin volts (V) is equal to the powerPin watts (W), divided by the currentIin amps (A):

V_{(V)}=P_{(W)}/I_{(A)}## AC single phase watts to volts calculation

The RMS voltage

Vin volts (V) is equal to the powerPin watts (W), divided by the power factorPFtimes the phase currentIin amps (A):

V_{(V)}=P_{(W)}/ (PF×I_{(A)})## AC three phase watts to volts calculation

## Calculation with line to line voltage

The line to line RMS voltage

V_{L-L}in volts (V) is equal to the powerPin watts (W), divided by square root of 3 times the power factorFPtimes the phase currentIin amps (A):

V_{L-L(V)}=P_{(W)}/ (√3 ×PF×I_{(A)}) ≈P_{(W)}/ (1.732 ×PF×I_{(A)})## Calculation with line to neutral voltage

The line to neutral RMS voltage

V_{L-N}in volts (V) is equal to the powerPin watts (W), divided by 3 times the power factorFPtimes the phase currentIin amps (A):

V_{L-N(V)}=P_{(W)}/ (3 ×PF×I_{(A)})
