What does one boiler horsepower represent?

One boiler horsepower is the rate of heat to evaporate 34.5 pounds of water per hour at 212°F, standardized as 33,475 BTU/h.

When should I use kilojoule/hour as a unit of power?

Kilojoule/hour is suitable for describing small to moderate energy rates over hourly timescales, such as in building physics or metabolic energy tracking.

Can boiler horsepower be used interchangeably with mechanical horsepower?

No, boiler horsepower is specific to steam generation and thermal power, and does not directly correspond to mechanical horsepower.

Browser-based and easy to use with no installation required.
Supports accurate thermal power unit translation for engineering and industrial contexts.

Examples

2 horsepower (boiler) equals 70628.4 kilojoule/hour [kJ/h].
0.5 horsepower (boiler) converts to 17657.1 kilojoule/hour [kJ/h].

Common Use Cases

Evaluating boiler capacities for industrial steam systems.
Converting boiler steam power ratings into standard energy flow units for HVAC design.
Comparing historic steam-generation equipment from marine or locomotive applications.

Tips & Best Practices

Ensure steady-state conditions similar to boiler rating standards when using conversions.
Use kilojoule per hour units for small to moderate power rates to maintain clarity.
Cross-check unit contexts, as boiler horsepower relates specifically to steam-evaporation rates.

Limitations

Boiler horsepower does not directly equate to mechanical or electrical horsepower without additional context.
Large energy rates expressed in kJ/h can be unwieldy without converting to watts or kilowatts.
Conversions assume steady operating conditions defined by boiler power ratings, not transient states.
