1. Convert 1 kW to the W base: 1 × 1,000 = 1,000 W.
2. Convert from W to hp: 1,000 ÷ 745.69987158 = 1.341022 hp.
3. Direct factor check: 1 × 1.34102209 = 1.341022 hp.

This is a unit conversion, not an electrical sizing calculation. Mechanical horsepower (hp) and metric horsepower (PS) are intentionally separate units.
