Kilowatts to horsepower formula

hp = kW × 1.34102209

Take the value in kilowatts.
Multiply it by 1.34102209 (the number of horsepower in one kilowatt).

Example: 100 kW × 1.34102209 = 134.102 hp.

Reverse formula (horsepower to kilowatts): kW = hp ÷ 1.34102209. Example: 100.577 hp ÷ 1.34102209 = 75 kW.

Quick mental estimate: multiply by about 1.3. For exact answers use the converter above.
