How to Convert Watts to Volts

To convert watts to volts, divide the power in watts by the current in amperes. This is derived from the electrical power formula: P = V × I, rearranged as V = P ÷ I. For example, a 100W device drawing 2A of current operates at 50 volts.

Common Conversions

• • 60W ÷ 0.5A = 120V (typical US household outlet)
• • 1000W ÷ 4.35A ≈ 230V (UK mains voltage)
• • 12W ÷ 1A = 12V (car battery accessory)
