Volts to Watts Calculator
Here you can understand how electrical power is calculated using voltage and current, then only you complete your task, project or whatever.
- Watts is a measurement rate of energy used or generated in an electrical system.
- The basic formula is: Watts = Volts × Amps (for DC circuits).
- For AC circuits, the formula becomes:
- Single-phase AC: Watts = Volts × Amps × Power Factor
- Three-phase AC: Watts = √3 × Volts × Amps × Power Factor
- Default pf accounts for efficiency in AC systems is from 0 and upto 1.
- This tool helps you calculate the power based on your circuit type and values.
