Watts to volts calculator
Watts (W) to volts (V) calculator.
Enter the power in watts, current in amps and press the Calculate button to get the voltage in volts:
DC watts to volts calculation
The voltage V in volts (V) is equal to the power P in watts (W), divided by the current I in amps (A):
V(V) = P(W) / I(A)
AC single phase watts to volts calculation
The RMS voltage V in volts (V) is equal to the power P in watts (W), divided by the power factor PF times the phase current I in amps (A):
V(V) = P(W) / (PF × I(A) )
AC three phase watts to volts calculation
Calculation with line to line voltage
The line to line RMS voltage VL-L in volts (V) is equal to the power P in watts (W), divided by square root of 3 times the power factor PF times the phase current I in amps (A):
VL-L(V) = P(W) / (√3 × PF × I(A) ) ≈ P(W) / (1.732 × PF × I(A) )
Calculation with line to neutral voltage
The line to neutral RMS voltage VL-N in volts (V) is equal to the power P in watts (W), divided by 3 times the power factor PF times the phase current I in amps (A):
VL-N(V) = P(W) / (3 × PF × I(A) )
