What does 1 MeV represent in joules?

One megaelectron-volt (MeV) equals exactly 1.602176634×10^-13 joule.

What is a kilocalorie (thermochemical) used for?

Kilocalorie (th) is commonly used to express food energy content and heat quantities in thermochemical and engineering contexts.

Why are converted values from MeV to kcal (th) so small?

Because megaelectron-volt units measure energy at atomic scales while kilocalorie (th) units measure energy on much larger thermal scales, resulting in very tiny equivalent values.
