Frequently Asked Questions
-
What does kilocalorie (th) measure?
-
Kilocalorie (th) measures energy, specifically thermochemical calories, commonly used for food energy content and heat quantities.
-
What is a megaelectron-volt (MeV)?
-
A megaelectron-volt is a unit of energy used in atomic and subatomic physics equal to one million electronvolts.
-
Why convert kilocalorie (th) to MeV?
-
This conversion bridges macroscopic energies like food energy with microscopic energy units used in nuclear and particle physics.
