What Is This Tool?

This converter transforms energy values from the thermochemical calorie (cal (th)), a historical energy unit, into kilojoules (kJ), the SI-derived standard for energy. It is ideal for interpreting and modernizing heat and thermochemical data.

How to Use This Tool?

  • Enter the energy amount in calorie (th) units
  • Select calorie (th) as the source unit and kilojoule as the target unit
  • Execute the conversion to see the energy expressed in kilojoules
  • Use the converted values for thermochemical analysis or engineering applications

Key Features

  • Converts thermochemical calories to kilojoules accurately using established rates
  • Supports users working with historical thermochemical and calorimetry data
  • Facilitates updating older energy measurements to modern SI units
  • Simple, browser-based interface for quick energy unit conversions

Examples

  • 10 calorie (th) equals 0.04184 kilojoule
  • 250 calorie (th) equals 1.046 kilojoule

Common Use Cases

  • Translating older thermochemical and calorimetry measurements to modern energy units
  • Converting specific heat capacity values from historical references
  • Comparing classical thermochemical data with contemporary energy data
  • Supporting energy quantification needs in chemical, physical, and engineering contexts

Tips & Best Practices

  • Confirm the original data uses the thermochemical calorie variant before converting
  • Cross-reference converted results with current SI units for consistency
  • Use kilojoules for standard scientific and engineering energy reporting
  • Be aware of different calorie definitions to prevent confusion during conversion

Limitations

  • Thermochemical calorie usage is mostly historical and rarely used in modern measurements
  • Current practical energy data usually rely on joules or kilojoules rather than calories
  • Multiple calorie types exist; this tool handles only the thermochemical calorie with a defined joule correspondence

Frequently Asked Questions

Why is the thermochemical calorie still used in some data?
It appears in historical thermochemical and calorimetry literature to provide consistent legacy conversions before widespread adoption of the joule.

What is the exact conversion rate between calorie (th) and kilojoule?
One thermochemical calorie equals exactly 0.004184 kilojoules.

Can I use this tool to convert other calorie types to kilojoules?
No, this converter specifically handles the thermochemical calorie variant and its fixed conversion to kilojoules.

Key Terminology

Thermochemical calorie (cal (th))
A unit of energy defined as exactly 4.184 joules, used historically in thermochemical data and older heat measurements.
Kilojoule (kJ)
An SI-derived energy unit equal to 1,000 joules, commonly used in scientific, engineering, and nutritional contexts.
Conversion Rate
The fixed factor used to transform one unit of energy into another, here 1 cal (th) equals 0.004184 kJ.
