3 Amps to Watts
3 amps is 360 watts at 120 volts and 720 watts at 240 volts (watts = amps × volts, at unity power factor).
3 Amps to Watts conversion table
| Voltage | Watts (PF 1.0) | Watts (PF 0.8) |
|---|---|---|
| 12 V DC | 36 W | — |
| 24 V DC | 72 W | — |
| 48 V DC | 144 W | — |
| 120 V AC | 360 W | 288 W |
| 208 V AC | 624 W | 499 W |
| 240 V AC | 720 W | 576 W |
| 277 V AC | 831 W | 665 W |
| 480 V AC | 1,440 W | 1,152 W |
PF = power factor. Resistive loads (heaters, incandescent lights) are PF 1.0; motors and compressors typically run PF 0.8-0.9. For a different value, use the interactive converter.
Frequently asked questions
360 watts (3 A × 120 V) for DC or resistive AC loads. With a 0.8 power factor (motors), the same current only delivers 288 W of real power.
