10 Amps to Watts
10 A = 1,200 W
10 amps at 120 volts is 1,200 watts (2,400 W at 240 V).
Step by step
- Use the formula watts = amps × volts (P = I × V).
- At 120 V: 10 × 120 = 1,200 W.
- At 240 V: 10 × 240 = 2,400 W.

How it works
Power in watts equals current in amps multiplied by voltage: P = I × V. On a standard US 120 V outlet each amp delivers 120 watts; on a 240 V circuit each amp delivers 240 watts. For breakers, plan continuous loads at no more than 80% of the rating — that is why a 15 A circuit is usually limited to about 1,440 W of continuous load.
