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.
DC Watts to Volts Calculation
V = W / I
V = Voltage in volts
W = Power in watts
I = Current in Amperes
Quick Trick: Voltage (V) = Power (W) / Current (I)!
AC Single Phase Watts to Volts Calculation
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!
AC Three Phase Watts to Volts Calculation
Calculation with Line to Line Voltage
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!
Calculation with Line to Neutral Voltage
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!
