How to use this tool
Enter the power and select its unit. Distinguish metric horsepower from mechanical horsepower, and do not enter kWh as though it were kW because they describe different quantities.
Results and examples
One kilowatt is 1000 watts. Metric horsepower is 735.49875 W, while mechanical horsepower is approximately 745.699872 W, so an unexplained HP label needs clarification.
Limitations
- Equipment efficiency and the difference between input power and shaft output are not inferred.
- Some conversion factors are rounded to the precision shown in the implementation.
