## Watts to volts calculator

We are offering Watts (W) to volts (V) calculator, to help you with your calculations.

All you need is to enter the value of power in watts, or the value of current in amps and then hit the = button to get the value of voltage in volts.

## DC watts to volts calculation

The value of voltage *V* in volts (V) is apparently equal to the value of power *P* in watts (W), which is divided by the value of current *I* measured in amps (A).

**V _{(V)} = P_{(W)} / I_{(A)}**

## AC single phase watts to volts calculation

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

**V _{(V)} = P_{(W)} / (PF × I_{(A)} )**

## AC three phase watts to volts calculation

#### The Calculation with line to line voltage

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

**V _{L-L(V)} = P_{(W)} / (√3 × PF × I_{(A)} )**

= **P _{(W)} / (1.732 × PF × I_{(A)} )**

#### The Calculation with line to neutral voltage

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

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