kW to hp formula

hp = kW × 1.34102
kW = hp × 0.7457

One mechanical horsepower is defined as 550 foot-pounds per second, which equals 745.7 watts. Dividing 1,000 watts by 745.7 gives 1.34102 hp per kilowatt.

Examples

  • 100 kW to hp: 100 × 1.34102 = 134.1 hp
  • 150 kW to hp: 150 × 1.34102 = 201.2 hp
  • 300 hp to kW: 300 × 0.7457 = 223.7 kW
  • 7.5 kW to hp: 7.5 × 1.34102 = 10.06 hp

hp vs. PS (metric horsepower)

European car makers often quote power in PS (German Pferdestärke), also written ch or CV. One PS is 735.5 W – about 1.4% less than one mechanical horsepower. So a car rated at 150 PS has 110 kW, or 148 hp.

Where kW is used

  • Electric vehicles: motor power and charging speed are given in kW.
  • European registrations: engine power is listed in kW on registration documents.
  • Electric motors and generators: almost always rated in kW.
