What is the calorie (IT) unit?

It is a historical energy unit defined as the heat needed to raise 1 gram of water by 1 °C under conditions of international steam tables, used in classical thermodynamics.

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

To align historical steam table energy data with thermochemical calorie definitions, enabling consistent comparisons and reporting in legacy scientific and engineering contexts.

Is the calorie (th) used in modern energy measurements?

While calorie (th) appears in older thermochemical data, modern work prefers SI joules for expressing energy.

What Is This Tool?

This tool allows you to convert energy measurements from the calorie (IT), an old unit used in classical thermodynamics and steam-engine computations, to the calorie (th), a thermochemical calorie defined with a fixed value in joules for consistent scientific use.

How to Use This Tool?

Enter the energy value in calorie (IT) you wish to convert.
Select 'calorie (IT)' as the input unit and 'calorie (th)' as the output unit.
Click the convert button to receive the equivalent calorie (th) value.
Use the results to compare, analyze, or report heat quantities consistently.

Key Features

Converts historical calorie (IT) values into thermochemical calorie (th) equivalents.
Based on the exact conversion rate: 1 cal (IT) equals 1.0006692161 cal (th).
Supports legacy engineering and thermochemical data reconciliation.
Browser-based, no installation required.
Helpful for interpreting older steam tables and calorimetry data.

Examples

Convert 5 calorie (IT) to calorie (th): Outputs 5.0033460805 calorie (th).
Convert 10 calorie (IT) to calorie (th): Outputs 10.006692161 calorie (th).

Common Use Cases

Analyzing and interpreting older steam tables and thermodynamic data.
Converting pre-SI engineering literature specific heats and enthalpies.
Reconciling historical calorie measurements for calorimetry and chemistry.
Digitizing legacy data sets and converting to SI units like joules.
Evaluating steam-engine and heat-engine performance from classical studies.

Tips & Best Practices

Always verify which calorie definition is used in your data before converting.
Use this converter primarily for legacy and historical datasets.
Cross-check converted values when precise energy measurements are critical.
Refer to SI units like joules for modern scientific applications.
Leverage this tool for educational and archival research purposes.

Limitations

The calorie (IT) is outdated and replaced largely by the joule in current practice.
Minor differences between calorie definitions require caution in precise work.
This conversion mainly addresses legacy data and is less relevant for modern usages.
Modern science prefers SI units, making calorie-based conversions less common.
