# Watts to Volts conversion

## Enter the power in watts, the current in amps and press the Calculate button:

 Direct Current (DC) Single Phase Alternating Current (AC) Three Phase Alternating Current (AC) Watts: W Amps: A Power factor: Power factor: Voltage result (volts): V
 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 the 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): V(L-N)(V) = P(W) / (3 * PF * I(A))
