How this is worked out

Brake horsepower is converted to kilowatts at 0.745699872 kW per horsepower, the mechanical horsepower definition.

Worked example

  • 150 bhp

150 × 0.7457

150 bhp is 111.9 kW

Assumptions and limits

  • Uses mechanical horsepower. Metric horsepower, written PS and common in European brochures, is about 1.4% smaller, so 150 PS is roughly 148 bhp.
  • A straight unit conversion. It says nothing about where in the rev range the power is produced, or whether the figure is measured at the crank or the wheels.
