Amps to Watts Converter
Convert electrical current in amps (A) to real power in watts (W). This requires knowing the voltage of the system and, for AC power, the power factor and phase configuration.

Ampere ↔ Watt
A
W
Calculation Formula
1,000 A × 120 V × 1 PF = 120,000 W
Worked Example
Convert 15 amps to watts at 120V (Single-Phase, PF=1):
15 A × 120 V × 1.0 = 1,800 Watts
Ampere to Watt Table
| A | W (at 120V) | W (at 230V) |
|---|---|---|
| 1 A | 120 W | 230 W |
| 5 A | 600 W | 1,150 W |
| 10 A | 1,200 W | 2,300 W |
| 15 A | 1,800 W | 3,450 W |
| 20 A | 2,400 W | 4,600 W |
| 30 A | 3,600 W | 6,900 W |
| 50 A | 6,000 W | 11,500 W |
Understanding the Conversion
Converting from amps to watts helps determine the actual power draw of a circuit or device, which is essential for sizing generators, inverters, and calculating energy costs.
