Formula
1 kW = 1.34102 hp
horsepower (mechanical) = kilowatts × 1.34102209 — reverse: kilowatts = horsepower (mechanical) × 0.7456998716
The factor is derived from the SI definitions of both units (base unit: W) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.
Worked examples
- 5 kW = 6.70511 hp
- 12.5 kW = 16.7628 hp
- 100 kW = 134.102 hp
