Watts to Volts Calculator
Convert electric power in Watts (W) to electrical potential in Volts (V).
How to Convert Watts to Volts
The formula to convert Watts to Volts depends on the type of current (DC or AC).
DC Volts Calculation Formula
For DC circuits, voltage (in Volts) is equal to the power (in Watts) divided by the current (in Amps).
V(V) = P(W) / I(A)
AC Volts Calculation Formula
For AC circuits, the Power Factor (PF) must be included.
Single Phase AC
V(V) = P(W) / (I(A) × PF)
Three Phase AC (Line-to-Line Voltage)
VL-L(V) = P(W) / (√3 × I(A) × PF)
Three Phase AC (Line-to-Neutral Voltage)
VL-N(V) = P(W) / (3 × I(A) × PF)
Calculation Example
Question: A device consumes 2400 Watts and draws 10 Amps of current. What is the voltage?
Answer:
V = 2400 W / 10 A = 240 Volts
