What does 1 MeV represent in terms of energy?

1 MeV equals one million electronvolts and corresponds to 1.602176634×10^-13 joule at atomic and subatomic scales.

Why convert MeV to kJ?

Converting MeV to kJ helps relate specialized particle physics energy values to standard units used in science, engineering, and nutrition.

Are MeV values practical for everyday energy calculations?

No, MeV is typically used for atomic-scale energies and is impractical for macroscopic energy applications typically measured in kilojoules.
