Volts to Watts: How to Calculate Power From Voltage (DC, AC, Three-Phase & Ohmic Loads)
You cannot get watts from volts alone. Learn P = V × I for DC, P = V × I × PF for single-phase AC, P = √3 × V × I × PF for balanced three-phase (line-to-line), and P = V² ÷ R for resistive loads — plus a free volts-to-watts calculator in your browser.
