What is the formula for converting engine net power to horsepower?

[AnnieDella]

Engine net power conversion to horsepower formula is 1 metric horsepower = 75 kilogram-force·meter/second = 735 watts. The following is relevant information about engines: 1. Concept: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. 2. Classification: Internal combustion engines, external combustion engines (meaning fuel burns outside the engine), gas turbines, jet engines.
