1 Amps to Watts
1 amps is 120 watts at 120 volts and 240 watts at 240 volts (watts = amps × volts, at unity power factor).
1 Amps to Watts conversion table
| Voltage | Watts (PF 1.0) | Watts (PF 0.8) |
|---|---|---|
| 12 V DC | 12 W | — |
| 24 V DC | 24 W | — |
| 48 V DC | 48 W | — |
| 120 V AC | 120 W | 96 W |
| 208 V AC | 208 W | 166 W |
| 240 V AC | 240 W | 192 W |
| 277 V AC | 277 W | 222 W |
| 480 V AC | 480 W | 384 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
120 watts (1 A × 120 V) for DC or resistive AC loads. With a 0.8 power factor (motors), the same current only delivers 96 W of real power.
