Convert between different horsepower units with precision
Mechanical Horsepower (HP): The most common unit, equal to approximately 745.7 watts. Originally developed by James Watt to compare steam engine output to draft horses.
Metric Horsepower (PS): Used in Europe and some other regions, equal to exactly 735.5 watts (75 kgf·m/s). Slightly less than mechanical HP.
Electrical Horsepower: Used for electric motors, equal to exactly 746 watts.
Boiler Horsepower: Used for boiler power output, equal to 33,475 BTU/hr (approximately 9,809.5 watts).
Kilowatts (kW): The SI unit of power, where 1 kW ≈ 1.341 mechanical HP.
Easily convert horsepower (HP) to kilowatts (kW), metric horsepower (PS), and other power units. A quick and reliable tool for engineers, mechanics, and anyone working with power values.
Horsepower is a unit of measurement used to express the rate at which work is done. It's commonly used to describe the power output of engines, particularly in vehicles and machinery. There are different types of horsepower, including mechanical HP, metric HP (PS), and electrical HP.
Horsepower values can vary depending on the system being used—mechanical, metric, boiler, or electrical. Converting HP to other units like kilowatts (kW), watts (W), or metric HP (PS) is essential when working across different countries or industries.
