How to Convert Watts to Volts

Watts (W) to volts (V) conversion requires current (I) via V = P / I, as watts measure power and volts measure electric potential.

V = W / I

V = Voltage in volts

W = Power in watts

I = Current in Amperes

Quick Trick: Voltage (V) = Power (W) / Current (I)!

V = W / (PF × I)

V = Voltage in volts

W = Power in watts

PF = Power Factor

I = Current in Amperes

Quick Trick: Divide by the Power Factor for AC calculations!

V = W / (√3 × PF × I)

V = Voltage in volts

W = Power in watts

PF = Power Factor

I = Current in Amperes

Quick Trick: Use √3 for three-phase calculations!

V = W / (3 × PF × I)

V = Voltage in volts

W = Power in watts

PF = Power Factor

I = Current in Amperes

Quick Trick: Divide by 3 for line to neutral calculations!
