Horsepower (hp) to Kilowatt (kW) Conversion
The conversion from horsepower (hp) to kilowatt (kW) is one of the most commonly used power unit conversions in engineering technology. Horsepower is primarily used for power ratings of automobiles, ships, and traditional mechanical equipment, while kilowatt is the power unit in the International System of Units, widely used in motors, power generation equipment, and modern industrial systems. Accurate unit conversion is crucial for equipment selection, performance comparison, and engineering design.
This tool provides professional hp to kW conversion functionality, supporting bidirectional conversion and real-time calculation, suitable for the daily work needs of automotive engineers, mechanical designers, electrical engineers, and equipment procurement personnel.
Conversion Formula
The conversion between horsepower (hp) and kilowatt (kW) is based on the standard definition:
Basic Formula:
- 1 hp = 0.745699872 kW
- 1 kW = 1.34102209 hp
Conversion Formulas:
- hp to kW: kW = hp × 0.745699872
- kW to hp: hp = kW × 1.34102209
