Amps to Watts Formula
Power in watts = current × voltage: W = A × V. This is a direct application of Ohm's Law for power.
Common examples at 120 V:
- 1 A = 120 W
- 5 A = 600 W
- 10 A = 1200 W
- 15 A = 1800 W
- 20 A = 2400 W
Understanding Electrical Power
When you know the current draw (amps) of a device and the supply voltage, you can calculate power consumption. This is useful for sizing generators, solar systems, and understanding electricity bills. Multiply watts by hours used to get watt-hours (Wh) of energy consumed.
AC Power Factor
For AC circuits with reactive loads (motors, compressors), true power = V × A × power factor (PF). Most household appliances have a PF close to 1. Industrial motors may have PF of 0.7–0.9, meaning actual power is lower than V × A (apparent power).
