What does horsepower (water) represent?

Horsepower (water) measures the theoretical mechanical power to move water against a head and is used in hydraulic applications.

How is kilojoule per hour used in energy measurements?

Kilojoule per hour quantifies energy transfer rates over hourly intervals and is applied in low-to-moderate rate heat transfer and metabolic energy calculations.

Why might I prefer watts over kilojoule per hour?

Watts are the standard SI unit for power and may be preferred for precision and regulatory reporting compared to kilojoule per hour.
