What is the Horsepower to Watts Converter?
The Horsepower (HP) to Watts (W) converter bridges traditional mechanical engineering and modern electrical standards. It translates the raw physical turning force of an engine into standard linear electrical output.
How It Works (Formula)
The calculator supports the three distinct definitions of HP. One Mechanical HP (US/UK) equals 745.699872 Watts. One Metric HP (Europe) equals slightly less at 735.49875 Watts. One Electrical HP equals exactly 746 Watts. The tool applies the correct multiplier based on your selection.
$$ P_{(\text{W})} = P_{(\text{Mechanic HP})} \times 745.699872 $$
The specific multiplication constant linking rotary mechanics to linear electricity.
How to Use It
Enter the power of the engine or motor in Horsepower (HP). Use the dropdown to specify whether it is Mechanical, Metric, or Electrical HP. The calculator will instantly multiply by the correct constant and output the raw Watts (W).
