What is the Watts to Horsepower Converter?
The Watts (W) to Horsepower (HP) converter is frequently used by mechanical engineers dealing with small electric motors (like those found in e-bikes, power tools, and lawnmowers). It translates base electrical wattage into a recognizable physical turning rating.
How It Works (Formula)
Because a single Horsepower is incredibly strong (roughly 746 Watts), converting upwards from Watts requires division. The calculator divides the inputted wattage by 745.699872 for Mechanical HP, or 735.49875 for Metric HP.
$$ P_{(\text{Mechanic HP})} = \frac{P_{(\text{W})}}{745.699872} $$
The specific division formula for converting linear electricity to rotary mechanics.
How to Use It
Enter the power consumption of the motor in Watts (W). Select the specific type of Horsepower you need (Mechanical, Metric, or Electrical). The tool will divide by the appropriate constant and output the HP. For example, a 1,500W motor yields roughly 2 HP.
