What does one nutritional Calorie represent?

One nutritional Calorie represents a kilocalorie, equal to 1,000 small calories, quantifying the energy from food and drink.

Why is the calorie (IT) considered historical?

The calorie (IT) was used in classical thermodynamics and steam engine calculations but is now largely superseded by the joule in scientific measurements.

How do I convert nutritional Calories to calorie (IT)?

Multiply the value in nutritional Calories by 1,000 to get the equivalent energy in calorie (IT).

What Is This Tool?

This unit converter transforms energy values from the nutritional Calorie, representing kilocalories commonly used in food energy, to the International Steam Table calorie (cal IT), a historical unit used in thermodynamics and steam engine calculations. It supports users in linking modern nutritional data with legacy engineering energy measurements.

How to Use This Tool?

Enter the energy value in Calorie (nutritional) units
Select Calorie (IT) [cal (IT), cal] as the target unit
Click convert to obtain the equivalent value in calorie (IT)

Key Features

Converts nutritional Calories (kilocalories) to International Steam Table calories accurately
Supports analysis across nutrition science and classical thermodynamics
User-friendly interface for quick and straightforward energy unit conversions

Examples

1 Calorie (nutritional) equals 1000 calorie (IT)
5 Calories (nutritional) convert to 5000 calorie (IT)

Common Use Cases

Interpreting energy data on food labels and nutrition databases
Converting historical thermodynamic data from steam tables
Integrating nutritional energy and classical engineering datasets for analysis

Tips & Best Practices
