What Is This Tool?

This converter transforms power values expressed in gigajoules per second (GJ/s), a large SI unit, into mechanical horsepower (hp, hp (UK)), a traditional imperial power unit. It helps translate large-scale scientific and engineering power ratings to more familiar horsepower units used in automotive, machinery, and industrial contexts.

How to Use This Tool?

Enter the power value in gigajoule/second (GJ/s) into the input field
Select the desired output unit as horsepower (hp, hp (UK))
Click the convert button to view the equivalent power in horsepower
Review and use the converted value for further analysis or specification
