What does 1 Btu (IT)/hour represent?

It is the power unit representing one International Table British thermal unit delivered per hour, commonly used to measure heat transfer rates.

When should I use calorie (th)/hour instead of Btu (IT)/hour?

Use calorie (th)/hour for reporting very small heat-transfer rates such as in laboratory or physiological contexts.

Are watts a better unit to express power than calorie (th)/hour?

Watts are the preferred SI unit for power, but calorie (th)/hour remains useful in specific applications involving small thermal power measurements.

What Is This Tool?

This tool converts power values from Btu (IT)/hour, a unit used to quantify heat transfer rates in heating systems and HVAC applications, to calorie (th)/hour, which measures heat transfer in smaller scales such as laboratory and physiological contexts.

How to Use This Tool?

Enter the power value in Btu (IT)/hour you wish to convert
Select the source unit as Btu (IT)/hour and the target unit as calorie (th)/hour
Click the convert button to see the equivalent value in calorie (th)/hour
Use the output for further calculations or reporting as needed

Key Features

Converts power between Btu (IT)/hour and calorie (th)/hour units
Supports applications in HVAC, laboratory calorimetry, and metabolic heat measurement
Provides clear examples for straightforward conversions
Browser-based and easy to use without installation

Examples

2 Btu (IT)/hour equals approximately 504.33 calorie (th)/hour
0.5 Btu (IT)/hour converts to about 126.08 calorie (th)/hour

Common Use Cases

Rating HVAC equipment and specifying furnace or boiler output
Measuring small heat transfer rates in chemical reaction calorimetry
Reporting metabolic heat production in physiological studies
Assessing heating or cooling of small devices using non-SI thermal units

Tips & Best Practices

Ensure you apply the appropriate unit based on the scale of heat transfer
Use this conversion for finer-scale heat rate measurements rather than large-scale systems
Cross-check unit selection to avoid misinterpretation of power levels
Remember that watts are the preferred SI unit in many industries

Limitations

Btu (IT)/hour is designed for larger heat transfer rates, while calorie (th)/hour applies to smaller values
Calorie is a non-SI unit and less common in some professional fields
Conversion accuracy relies on exact unit definitions; minor differences may occur
Using the wrong unit can lead to inaccurate representation of thermal power
