What is Btu (IT)/hour used for?

It measures the rate of heat transfer commonly used in HVAC equipment capacity rating, boiler output specification, and heating system design.

How is boiler horsepower defined?

Boiler horsepower represents the thermal power needed to evaporate 34.5 pounds of water per hour at 212°F and is standardized as 33,475 BTU/h.

Can I use this conversion for mechanical horsepower?

No, this conversion applies only to thermal power and steam generation contexts, not mechanical horsepower calculations.

How to Convert from Btu (IT)/hour [Btu/h] to Horsepower (boiler)?

What Is This Tool?

This unit converter enables users to translate power values from Btu (IT)/hour, a common thermal power unit in HVAC and heating applications, into boiler horsepower, the standard for rating steam capacity in industrial boilers.

How to Use This Tool?

Enter the value in Btu (IT)/hour that you want to convert
Select Btu (IT)/hour as the source unit and horsepower (boiler) as the target unit
Click the convert button to see the equivalent power in boiler horsepower
Use the results to compare boiler capacities or evaluate heating system specifications

Key Features

Converts thermal power from Btu (IT)/hour to boiler horsepower using standardized conversion rates
Supports heat transfer and steam generation capacity calculations
Useful for HVAC design, boiler performance evaluation, and industrial application comparisons
Browser-based and easy to use without requiring manual calculations

Examples

10,000 Btu (IT)/hour converts to approximately 0.298762 horsepower (boiler)
50,000 Btu (IT)/hour is equivalent to about 1.49381 horsepower (boiler)

Common Use Cases

Rating HVAC equipment and specifying capacity for furnaces or air conditioners
Determining boiler, water heater, or gas-furnace heat output
Estimating building heat loss or gain and sizing heating system components
Comparing steam generation capacity in industrial boilers and heating plants
Assessing boiler performance in marine and locomotive contexts

Tips & Best Practices

Ensure the conversion applies only within heating and steam generation contexts
Confirm operating conditions align with the standard boiler horsepower definition
Use this tool for thermal power comparisons, not mechanical horsepower measurements
Double-check input values for accuracy before converting

Limitations

Boiler horsepower is defined based on evaporation of water at specific conditions; variations may impact precise equivalence
Conversion is mainly relevant for thermal and steam power and not suitable for mechanical horsepower metrics unrelated to heat
Different boiler designs or operating environments may require additional considerations beyond simple conversion
