What does 1 MeV represent in joules?

One megaelectronvolt (MeV) equals exactly 1.602176634×10^-13 joules.

Why use kilocalorie (IT) instead of other calorie units?

Kilocalorie (IT) is based on the international-table calorie, widely used in thermodynamics and engineering with a defined energy value of 4,186.8 joules per kcal (IT).

In what contexts is converting MeV to kcal (IT) important?

This conversion helps interpret subatomic particle energies in terms of thermal energy, useful in nuclear physics, calorimetry, engineering heat calculations, and nutrition energy literature referencing the international-table calorie.
