Tips for the Power Converter

  • "hp" here is mechanical (imperial) horsepower, the figure used for US car and engine specs.

Example: Power Converter

Converting a 200 hp engine rating to kilowatts

  • Value: 200 hp
  • Convert to: Kilowatts

Result: 149.1 kW

1 mechanical horsepower = 0.7457 kW, so 200 × 0.7457 ≈ 149.1 kW.
