What does horsepower (boiler) measure?

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

Why convert horsepower (boiler) to milliwatt?

Converting to milliwatt allows translating large-scale thermal power into smaller electrical power units for use in engineering fields such as electronic and optical device design.

Is the conversion exact for electrical applications?

No, the conversion is approximate because horsepower (boiler) references thermal conditions, so direct electrical power equivalence should be interpreted carefully.
