What does metric horsepower measure?

Metric horsepower measures power as the rate of energy transfer or work done per unit time by an engine or motor.

Are there any challenges in converting these units?

Yes, the huge difference in scale results in very large numeric values that can be difficult to handle without scientific notation.
