Kilowatt to horsepower formula
horsepower = kilowatts × 1.3410220896 — 1 kW = 1.34102209 hp. Both units are defined exactly (NIST SP 811); the factor above is rounded to 10 decimals, and the converter uses the full-precision ratio.

Generators and power tools
Standby generators are rated in kW of electrical output, while their engines are rated in hp — and about 2 hp of engine is needed per kW of generator output once losses are counted. European power tools and motors list kW: a 2.2 kW table saw motor is just under 3 hp.
