What does horsepower (boiler) measure?

Horsepower (boiler) measures the thermal power based on the heat rate required to evaporate a specific amount of water per hour at 212°F, commonly used to rate steam boilers.

Why convert horsepower (boiler) to Btu (th)/minute?

Converting to Btu (th)/minute provides a more detailed thermal energy transfer rate per minute useful for heating capacity calculations and equipment design.

Is Btu (th)/minute suitable for all power measurements?

No, Btu (th)/minute specifically measures thermal power and is not appropriate when mechanical or electrical power units are needed.
