What is the thermochemical calorie (cal (th))?

It is a unit of energy defined exactly as 4.184 joules, used historically in thermochemical measurements and older scientific data.

How is a nutritional Calorie different from a calorie (th)?

A nutritional Calorie (capital C) is a kilocalorie equal to 1,000 small calories, used to quantify energy from food, whereas calorie (th) is the thermochemical calorie used in older scientific contexts.

Can I use this converter for other calorie definitions?

No, this tool specifically converts between the thermochemical calorie and the nutritional kilocalorie and is not applicable to other calorie types.

What Is This Tool?

This converter transforms energy values from the thermochemical calorie (cal (th)), an older unit used primarily in historical thermochemical data, into nutritional Calories (kcal), the unit used to measure food energy. It helps bridge the gap between scientific literature and nutrition science by converting these distinct energy units.

How to Use This Tool?

Enter the energy value in calorie (th) or cal (th).
Select the target unit as Calorie (nutritional).
Click convert to see the equivalent energy in nutritional Calories.
Use the result for food energy calculations or dietary assessments.

Key Features

Converts thermochemical calories to nutritional kilocalories with a precise fixed conversion rate.
Simple user interface to input energy values and obtain instant results.
Ideal for handling historical thermochemical data and nutritional information.
Browser-based tool that needs no installation, accessible anytime.

Examples

Convert 500 cal (th) to nutritional Calories: 500 × 0.0009993312 = 0.4997 Calorie (nutritional).
Convert 1000 cal (th) to nutritional Calories: 1000 × 0.0009993312 = 0.9993 Calorie (nutritional).

Common Use Cases

Interpreting heat released or absorbed in older calorimetry reports.
Comparing specific heat capacity data from historical scientific literature.
Converting thermochemical enthalpy values into nutrition-related energy units.
Calculating energy intake from food labels using kilocalories.
Planning diets and tracking energy consumption for weight management.

Tips & Best Practices

Always verify unit capitalization to distinguish calorie (th) from Calorie (nutritional).
Use this conversion only when dealing with thermochemical calorie and nutritional kilocalorie units.
Refer to nutritional energy metrics for diet planning and physical activity calculations.
Keep in mind this conversion is based on exact definitions to ensure consistent results.

Limitations

The thermochemical calorie is largely historical and less common in modern measurements.
Nutritional Calories denote kilocalories and should not be confused with other calorie definitions.
This conversion is specific to thermochemical calories and nutritional kilocalories only.
Accuracy depends on correct unit identification and context of use.
