What does 1 Calorie (nutritional) represent?

1 Calorie (nutritional) equals 1 kilocalorie, which is 1,000 small calories, defined as 4,184 joules of energy available from food.

Why convert nutritional Calories to attojoules?

This conversion expresses macroscopic dietary energy in extremely small units useful for physics and nanoscale energy studies.

Is the attojoule unit useful for everyday food energy tracking?

No, the attojoule is used mainly in specialized scientific fields and is not practical for daily nutrition or food science.

How to Use This Tool?

Enter the energy value in nutritional Calories (kcal).
Select the source unit as Calorie (nutritional) and the target unit as attojoule [aJ].
Initiate the conversion to see the equivalent energy in attojoules.
Use the converted result for scientific or educational purposes related to nanoscale energy.

Key Features

Converts from nutritional Calories (kcal) to attojoules (aJ).
Expresses large food energy quantities in extremely small energy units.
Useful for connecting nutrition science with quantum and molecular energy scales.
Browser-based and easy to use without special software.

Examples

2 Calories (nutritional) equals 8,373,600,000,000,000,000,000 aJ.
0.5 Calorie (nutritional) converts to 2,093,400,000,000,000,000,000 aJ.

Common Use Cases

Expressing food energy amounts in quantum-scale energy units for interdisciplinary research.
Studying energy at molecular and atomic levels connecting nutrition and physics.
