Convert megaelectron-volt to kilocalorie (IT)
Please provide values below to convert megaelectron-volt [MeV] to kilocalorie (IT) [kcal (IT)], or Convert kilocalorie (IT) to megaelectron-volt.
1 MeV = 3.8267e-17 kcal (IT). To convert megaelectron-volt to kilocalorie (IT), multiply the value by 3.8267e-17; to go the other way, divide by it (1 kcal (IT) = 2.6132e+16 MeV). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 MeV = 3.8267e-17 kcal (IT)
- 1 kcal (IT) = 2.6132e+16 MeV
- 10 MeV = 3.8267e-16 kcal (IT)
- 100 MeV = 3.8267e-15 kcal (IT)

Megaelectron-Volt
A megaelectron-volt (MeV) is a unit of energy equal to one million electron-volts, commonly used in nuclear and particle physics to express the energy of particles.
History/Origin
The megaelectron-volt was introduced as a convenient unit for expressing high-energy particles in physics, particularly after the development of particle accelerators in the mid-20th century, replacing the electron-volt for larger energy scales.
Current Use
Today, the MeV is widely used in nuclear physics, particle physics, and astrophysics to quantify the energy of subatomic particles, nuclear reactions, and cosmic phenomena.
Kilocalorie (It)
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 measure of heat energy, primarily used in nutrition and thermodynamics. It became standard in dietary contexts to quantify food energy intake.
Current Use
Today, the kilocalorie is widely used in nutrition to express the energy content of foods and beverages, and in scientific contexts related to energy measurement in biological and physical systems.
