Horsepower Unit Conversions

Horsepower TypeEquivalent in Watts
Electrical HP746 W
Mechanical HP745.69987 W
Metric HP735.49875 W

Formula

HP=WHPvalueHP = \frac{W}{HP_{value}}

where:

  • HPHP = Horsepower
  • WW = Power in Watts
  • HPvalueHP_{value} = Value of one HP unit (see conversion table above)

Inputs
