Amps to Watts Calculator
Convert between Electrical Current (Amps) and Power (Watts) for DC, Single Phase AC, and Three Phase AC circuits.
Formulas Used
- DC: Watts = Amps × Volts
- AC Single Phase: Watts = Amps × Volts × Power Factor
- AC Three Phase: Watts = √3 × Amps × Volts × Power Factor
What is Power Factor?
In AC circuits, Power Factor (PF) represents the ratio of real power to apparent power. Resistive loads (heaters, lights) have a PF of 1.0. Inductive loads (motors) typically have a PF between 0.8 and 0.9.
