Convert electron-volt to kilocalorie (th)
Please provide values below to convert electron-volt [eV] to kilocalorie (th) [kcal (th)], or Convert kilocalorie (th) to electron-volt.
1 eV = 3.8293e-23 kcal (th). To convert electron-volt to kilocalorie (th), multiply the value by 3.8293e-23; to go the other way, divide by it (1 kcal (th) = 2.6114e+22 eV). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 eV = 3.8293e-23 kcal (th)
- 1 kcal (th) = 2.6114e+22 eV

Electron-Volt
An electron-volt (eV) is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing atomic and subatomic energies, especially in quantum physics and particle physics, replacing larger units like the joule for small-scale energies.
Current Use
The electron-volt is widely used in physics and chemistry to quantify energies at the atomic and subatomic levels, such as in spectroscopy, particle physics, and quantum mechanics, due to its convenience in expressing small energy values.
Kilocalorie (Th)
A kilocalorie (kcal) is a unit of energy equal to 1,000 calories, commonly used to measure the energy content of food and beverages.
History/Origin
The kilocalorie originated in the 19th century as a unit to quantify heat energy, especially in nutrition and thermodynamics. It was widely adopted in the early 20th century for dietary energy measurement.
Current Use
Today, the kilocalorie is primarily used in nutrition to express the energy content of food and drinks, although it is often simply called a 'calorie' in everyday language.
