What is the nutritional Calorie unit?

It represents the kilocalorie used in food energy, equal to 1000 small calories and defined as 4,184 joules.

Why convert to the thermochemical calorie?

To compare or translate energy values with older calorimetric data or thermochemistry literature.

Is the thermochemical calorie still used today?

It is mostly superseded by the joule in modern science but still appears in historical data and educational contexts.

How to Convert from Calorie (nutritional) to Calorie (th) [cal (th)]?

Learn how to convert energy values from the nutritional Calorie unit used in food energy to the thermochemical calorie (cal (th)) for applications in calorimetry and thermochemistry.

What Is This Tool?

This unit converter transforms energy measurements from the nutritional Calorie, commonly used in food and dietetics, to the thermochemical calorie unit that is traditional in calorimetry and heat capacity contexts.

How to Use This Tool?

Enter the energy value in calorie (nutritional) units.
Select the target unit as calorie (th) [cal (th)].
Click the convert button to get the equivalent thermochemical calorie value.
Review the result for applications like calorimetry or historical data comparisons.

Key Features

Converts nutritional Calories (kcal) to thermochemical calories (cal (th)).
Uses a precise conversion factor between calorie definitions.
Supports energy calculations for nutrition and thermochemical research.
Browser-based and easy to use with no installation required.

Examples

2 calorie (nutritional) equals approximately 2001.3384 calorie (th) [cal (th)].
0.5 calorie (nutritional) converts to about 500.3346 calorie (th) [cal (th)].

Common Use Cases

Translating food energy values for compatibility with older thermochemical data.
Planning diets and tracking daily energy intake in nutrition science.
Analyzing heat absorption or release in historical calorimetry experiments.
Teaching specific heat capacity concepts using traditional units.

Tips & Best Practices

Use this tool primarily for harmonizing nutritional energy data with thermochemical literature.
Keep in mind the calorie (th) is mostly replaced by the joule in contemporary science.
Apply the exact conversion factor here to maintain precision.
Cross-check energy calculations when used for sensitive scientific or educational purposes.

Limitations

The calorie (th) unit is outdated compared to the SI joule and is mainly for historical reference.
Small differences in definitions mean approximate conversions may cause minor errors.
Conversions may not be suitable for high-precision modern scientific measurements.
