# Watts to volts calculator

## Watts to volts calculator

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.

 Select current type: DC AC - Single phase AC - Three phase Enter power in watts: W Enter current in amps: A Voltage result in volts: V

## 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 VL-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).

VL-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 VL-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).

VL-N(V) = P(W) / (3 × PF × I(A) )
