Amps to Watts Calculator
Convert electrical current (Amperage) to power (Wattage). Supports Direct Current (DC), Single Phase AC, and Three Phase AC.
Current & Voltage
Use 1.0 for resistive loads (heaters), 0.8 for motors.
Common Power Conversions (at 120V)
15 Amps1,800 Watts
20 Amps2,400 Watts
30 Amps3,600 Watts
50 Amps6,000 Watts
Understanding Power Factor
In Alternating Current (AC) circuits, power factor is a measure of efficiency.
Resistive Loads (PF = 1.0)
Devices that generate heat or light (e.g., toasters, incandescent bulbs, electric heaters). All current is doing useful work.
Inductive Loads (PF < 1.0)
Devices with motors or coils (e.g., refrigerators, fans, air conditioners). Some current creates magnetic fields instead of doing direct work.
