- 1. Convert 1 hp to the W base: 1 × 745.69987158 = 745.69987158 W.
- 2. Convert from W to kW: 745.69987158 ÷ 1,000 = 0.7457 kW.
- 3. Direct factor check: 1 × 0.74569987 = 0.7457 kW.
This is a unit conversion, not an electrical sizing calculation. Mechanical horsepower (hp) and metric horsepower (PS) are intentionally separate units.

A quick note before you use the number
Power-unit conversion does not calculate electrical current, apparent power, efficiency or power factor. Use the dedicated electrical calculators for those relationships.
