What does horsepower (boiler) measure?

Horsepower (boiler) measures thermal power based on the heat rate needed to evaporate a fixed amount of water at 212°F, standardized for steam boiler capacity.

Why convert horsepower (boiler) to calorie (th)/hour?

Conversion enables translating large steam boiler power into smaller heat-transfer units useful for laboratory measurements or physiological heat production.

Is calorie (th)/hour an SI unit?

No, calorie (th)/hour is a non-SI thermal power unit; the watt is the preferred SI unit for power.
