How to convert power units
Watts × 1 ÷ 1000 = Kilowatts. Factors are relative to watts.
Multiply your input by its scale factor, then divide by the output unit’s factor. All factors below are expressed in watts per one unit. Some factors have been rounded to the precision shown.
| Unit | Factor in watts |
|---|---|
| Watts | 1 |
| Kilowatts | 1000 |
| Megawatts | 1000000 |
| Gigawatts | 1000000000 |
| Mechanical horsepower | 745.699871582 |
| Metric horsepower | 735.49875 |
| BTU (IT) per hour | 0.2930710701722222 |
| Foot-pounds per second | 1.3558179483314 |
Conventions
These are scale conversions within a single measurement dimension. They do not convert between different physical quantities.
