What does horsepower (boiler) measure?

Horsepower (boiler) measures the thermal power needed to evaporate 34.5 pounds of water per hour at 212°F, indicating boiler steam capacity.

Why convert horsepower (boiler) to joule/hour?

Converting to joule/hour helps express boiler power as energy transferred over time in SI-related units, useful for precise engineering and scientific analysis.

Are joule/hour and watt the same units?

No, joule/hour indicates energy transferred per hour, while watt is joule per second; joule/hour values are much smaller and convert to watts by dividing by 3600.

How to Convert from Horsepower (boiler) to Joule/hour [J/h]

Limitations

Joule/hour is a very small power unit, causing large result values that may seem impractical
Joule/hour is not a standard SI power unit, so watts or kilowatts are often preferred
Boiler horsepower definition relies on water evaporation at 212°F and may not apply to other fluids or temperatures
Users must ensure numerical results fit their application context given unit specificity
