What Is This Tool?
This unit converter helps transform power values from Btu (IT)/hour, a common heat transfer rate unit in HVAC and heating systems, to Btu (th)/second, a unit measuring thermal energy flow in energy conversion and cooling systems.
How to Use This Tool?
-
Enter the value in Btu (IT)/hour you wish to convert.
-
Select Btu (IT)/hour as the input unit and Btu (th)/second as the output unit.
-
Click convert to get the equivalent value in Btu (th)/second.
Key Features
-
Converts power between Btu (IT)/hour and Btu (th)/second units.
-
Ideal for analyzing heat transfer rates in HVAC, boilers, and heat exchangers.
-
Browser-based and simple to use for quick thermal energy calculations.
Examples
-
Converting 10 Btu (IT)/hour results in 0.002779637 Btu (th)/second.
-
Converting 100 Btu (IT)/hour results in 0.02779637 Btu (th)/second.
Common Use Cases
-
Evaluating HVAC equipment capacity for heating or cooling output.
-
Specifying heat output for boilers, water heaters, and furnaces.
-
Sizing heat exchangers and assessing building heat loss or gain.
-
Comparing transient heat transfer rates in energy system tests.
Tips & Best Practices
-
Ensure input values correspond to steady-state conditions for accuracy.
-
Use the converter to align unit systems when working with different Btu definitions.
-
Consider system-specific standards when interpreting converted results.
Limitations
-
Variations between Btu (IT) and Btu (th) definitions may impact precision.
-
Conversion assumes steady-state; fluctuating heat loads need further analysis.
-
Calibration and system-specific standards should be applied for accurate comparisons.
Frequently Asked Questions
-
Why convert from Btu (IT)/hour to Btu (th)/second?
-
Converting allows comparison or specification of heat transfer rates with finer time resolution and aligns values with thermochemical British thermal units used in certain systems.
Key Terminology
-
Btu (IT)/hour
-
A power unit representing one International Table British thermal unit transferred per hour, commonly used in heat transfer rate measurements.
-
Btu (th)/second
-
A power unit that measures thermal energy flow as one thermochemical British thermal unit delivered each second, used in heating and energy systems.
-
Heat Transfer Rate
-
The amount of thermal energy exchanged per unit of time during heating or cooling processes.
