Mechanical horsepower conventions
Power describes work done per unit time. The horsepower convention matters: this calculator uses mechanical horsepower, not metric horsepower or electrical efficiency assumptions.
One mechanical horsepower is about 745.6998716 watts. Conversion of rated power does not measure actual power consumption or performance.
Reference: NIST conversion factors. Calculation and display rounding are separate. See how we calculate.
Which horsepower standard?
This converter uses mechanical horsepower (hp(I)) only. Other horsepower definitions produce different numerical answers for the same kilowatts. Confirm the convention on the source label before comparing ratings.
| Horsepower convention | 1 kW in hp | 5 kW in hp | Converter support |
|---|---|---|---|
| Mechanical horsepower, hp(I) | 1.341022 hp | 6.70511 hp | Live converter |
| Electric horsepower, hp(E) | 1.340483 hp | 6.702413 hp | For comparison only |
| Metric horsepower, hp(M) | 1.359622 hp | 6.798108 hp | For comparison only |
| Boiler horsepower, hp(S) | 0.101942 hp | 0.50971 hp | For comparison only |
Mechanical hp uses approximately 745.699871582 W per hp; electric hp uses 746 W, metric hp uses 735.49875 W and boiler hp uses 9,809.5 W per hp by the conventions shown. Display results are rounded. Compare horsepower definitions.
