What is a kilocalorie (th)?

A kilocalorie (th), symbol kcal (th), is an energy unit equal to 1,000 thermochemical calories and defined exactly as 4,184 joules, commonly used in food energy content and thermochemical contexts.

Why convert kilocalorie (th) to calorie (IT)?

Conversions help interpret historical engineering and thermodynamic data based on steam table calories, aligning legacy data with modern analysis.

Is calorie (IT) still commonly used?

No, the calorie (IT) is mostly replaced by the joule but remains important for analyzing historical documents and legacy engineering datasets.

Examples

Convert 2 kilocalorie (th) to calorie (IT): 2 × 999.3312314894 = 1998.6624629788 calorie (IT)
Convert 0.5 kilocalorie (th) to calorie (IT): 0.5 × 999.3312314894 = 499.6656157447 calorie (IT)

Common Use Cases

Labeling food and nutrition to express caloric content accurately
Planning diets and studying metabolic energy intake and expenditure
Examining older thermochemical or engineering sources that cite kcal alongside SI units
Interpreting historical steam tables and thermodynamic data for heat-engine performance
Converting legacy engineering energy data to align with modern SI-based units

Tips & Best Practices

Always verify you are using the calorie (IT) definition as the target unit to avoid confusion with other calorie variants
Use this tool primarily for legacy data or contexts referencing thermochemical calories and steam table calories
Cross-check converted results when working with critical engineering calculations or research
Remember that this conversion tool is designed for specific conditions defined in classical thermodynamics

Limitations

Calorie (IT) is a historical unit largely superseded by the joule, so conversions are mainly relevant to legacy datasets
Differences among calorie definitions can lead to minor discrepancies if the specified calorie (IT) is not used
The conversion assumes exact thermochemical and steam table conditions which may not apply universally in all thermal processes
