Power
Convert watt (W) to mechanical horsepower (hp). Power is energy per unit time — the rating of pumps, compressors, motors, and heat duties.
1 W = 0.001341022 hp
To convert watt to mechanical horsepower, multiply the W value by 0.001341022. To go the other way, divide by 0.001341022 (or multiply by 745.6999).
| W | hp |
|---|---|
| 1 | 0.001341022 |
| 2 | 0.002682044 |
| 5 | 0.00670511 |
| 10 | 0.01341022 |
| 25 | 0.03352555 |
| 50 | 0.0670511 |
| 100 | 0.1341022 |
| 250 | 0.3352555 |
| 500 | 0.670511 |
| 1000 | 1.341022 |
Rotating-equipment duties are quoted in kW or hp; heat duties in kW, MW, or BTU/hr.
Electrical input, shaft power, and hydraulic power differ by the efficiencies between them — label which one a number refers to.
Worked example. A power of 100000 W is 134.1022 hp.
Multiply the value in W by 0.001341022 to get hp. For example, 10 W = 0.01341022 hp.
1 W equals 0.001341022 hp.
