Volts to Watts Calculator
Instantly convert volts to watts using this free online calculator. Supports DC, single-phase, and three-phase AC with formula, examples, and table.
Quick Intro: Convert Volts to Watts
To convert volts to watts, you need to know the current (amperes) and power factor (for AC). The formula varies based on the type of circuit—DC, single-phase AC, or three-phase AC. This calculator simplifies those calculations for you.
Formula to Convert Volts to Watts
- DC:
Watts = Volts × Amps - Single Phase AC:
Watts = Volts × Amps × PF - Three Phase AC:
Watts = √3 × Volts × Amps × PF
