What does metric horsepower measure?

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

Why use kilojoule/hour instead of watts?

Kilojoule per hour expresses energy transfer over an hourly period, making it useful in contexts like building physics or metabolic energy tracking where hourly rates are preferred.

Is this conversion suitable for all power levels?

Kilojoule/hour units are best for small to moderate power levels; very large horsepower values may produce large, less practical results in kJ/h.
