5 Amps to Watts
5 A = 600 W
5 amps at 120 volts is 600 watts (1,200 W at 240 V).
Step by step
- Use the formula watts = amps × volts (P = I × V).
- At 120 V: 5 × 120 = 600 W.
- At 240 V: 5 × 240 = 1,200 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.
