What does calorie (th)/hour measure?

It measures thermal power as the rate of heat transfer equal to one thermochemical calorie delivered per hour.

Why convert between calorie (th)/hour and calorie (IT)/hour?

Because they use slightly different calorie definitions, converting helps interpret and compare heat transfer rates accurately.

Can these units be converted to watts?

Yes, both units relate to watts since they represent power, but watts are the standard SI unit preferred for most applications.

What Is This Tool?

This converter facilitates the transformation of power measurements from calorie (th)/hour, a thermochemical calorie-based unit, to calorie (IT)/hour, which uses the International Table calorie. Both units measure small heat-transfer rates, often in scientific and technical scenarios.

How to Use This Tool?

Enter the value in calorie (th)/hour that you want to convert
Select if necessary the source unit as calorie (th)/hour and target unit as calorie (IT)/hour
Click the convert button to get the equivalent value
Review the converted result based on the specific conversion rate

Key Features

Converts thermal power from calorie (th)/hour to calorie (IT)/hour
Uses precise conversion rate based on calorie definitions
Ideal for scientific, technical, and historical heat-transfer data
Supports interpretation of low-level heat production and transfer
Browser-based and easy to use without installation

Examples

5 calorie (th)/hour equals approximately 4.997 calorie (IT)/hour
10 calorie (th)/hour converts to about 9.993 calorie (IT)/hour

Common Use Cases

Reporting small heat-transfer rates in laboratory calorimetry or chemical reactions
Estimating metabolic or physiological heat production using calories per hour
Analyzing low heating or heat-loss rates in small devices or components
Interpreting historical technical documents using calorie units
Performing thermal tests on materials and experimental setups

Tips & Best Practices

Always ensure units are clearly identified before converting
Use conversion results to compare technical data with accuracy
Be aware of the small difference between these units for precise measurements
Consider converting to watts for standardized or regulatory purposes
Apply this tool to support scientific analysis and reporting

Limitations

The difference between calorie (th)/hour and calorie (IT)/hour is minor but important in precise applications
Both units are non-SI and less common than watts, the preferred power unit
Conversions might still require verification when dealing with strict regulatory or scientific standards
