What is an electron-volt used for?

Electron-volt is used to describe energies at atomic, molecular, nuclear, and particle physics scales, such as binding energies and reaction energies.

Why convert electron-volts to kilocalories (IT)?

Conversions help relate tiny atomic-scale energies to macroscopic heat and energy units familiar in thermodynamics and engineering.

Are kilocalorie (IT) and other calorie units the same?

No, kilocalorie (IT) is based on the international-table calorie definition, which can differ from other calorie conventions used especially in nutrition.

How to Convert from Electron-volt [eV] to Kilocalorie (IT) [kcal (IT)]?

10 electron-volts (eV) correspond to 3.8267331470334e-22 kilocalorie (IT) [kcal (IT)].

Common Use Cases

Describing tiny energy values from atomic or particle physics in thermodynamic units.
Performing engineering heat-balance and calorimetry calculations involving microscopic energies.
Relating particle-scale energy measurements to caloric units used in thermodynamics and older literature.

Tips & Best Practices

Ensure proper unit selection to avoid confusion between different calorie definitions.
Understand that converted values are very small due to differing energy scales of the units.
Use this conversion mainly for theoretical calculations or precise scientific work involving microscopic energies.

Limitations

Electron-volt measures microscopic-scale energies, while kilocalorie (IT) applies at macroscopic scales, resulting in extremely small converted values.
The kilocalorie (IT) unit is based on the international-table calorie, differing from other calorie definitions used in nutrition, requiring careful unit convention adherence.
