## Volts to watts calculator

Volts (V) to watts (W) calculator.

Enter the voltage in volts, current in amps and press the

Calculatebutton to get the power in watts:## DC volts to watts calculation formula

The power

Pin watts (W) is equal to the voltageVin volts (V), times the currentIin amps (A):

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

The power

Pin watts (W) is equal to the power factorPFtimes the phase currentIin amps (A), times the RMS voltageVin volts (V):

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

## Calculation with line to line voltage

The power

Pin watts (W) is equal to square root of 3 times the power factorPFtimes the phase currentIin amps (A), times the line to line RMS voltageV_{L-L}in volts (V):

P_{(W)}=√3 ×PF×I_{(A)}×V_{L-L(V)}≈ 1.732 ×

PF×I_{(A)}×V_{L-L(V)}## Calculation with line to neutral voltage

The power

Pin watts (W) is equal to 3 times the power factorPFtimes the phase currentIin amps (A), times the line to neutral RMS voltageV_{L-N}in volts (V):

P_{(W)}= 3 ×PF×I_{(A)}×V_{L-N(V)}
