Power
Convert mechanical horsepower (hp) to kilowatt (kW). Power is energy per unit time — the rating of pumps, compressors, motors, and heat duties.
1 hp = 0.7456999 kW
To convert mechanical horsepower to kilowatt, multiply the hp value by 0.7456999. To go the other way, divide by 0.7456999 (or multiply by 1.341022).
| hp | kW |
|---|---|
| 1 | 0.7456999 |
| 2 | 1.4914 |
| 5 | 3.728499 |
| 10 | 7.456999 |
| 25 | 18.6425 |
| 50 | 37.28499 |
| 100 | 74.56999 |
| 250 | 186.425 |
| 500 | 372.8499 |
| 1000 | 745.6999 |
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 134.1022 hp is 100 kW.
Multiply the value in hp by 0.7456999 to get kW. For example, 10 hp = 7.456999 kW.
1 hp equals 0.7456999 kW.
