What does 1 MeV represent in joules?

One megaelectron-volt (MeV) equals approximately 1.602176634 × 10⁻¹³ joules (J).

In which fields is MeV to joule conversion commonly used?

This conversion is widely employed in nuclear physics, particle physics, medical imaging such as PET, accelerator design, and radiation detection.

Why do converted values from MeV to joules appear very small?

Because megaelectron-volts measure atomic-scale energies, their equivalents in joules are very small decimal values requiring careful notation.
