How to Convert Megaelectronvolts to Kilocalories
The megaelectronvolt and kilocalorie are both units of energy. By definition, 1 kilocalorie equals exactly 2.6114473968e16 megaelectronvolts. This means to convert megaelectronvolts to kilocalories, you divide by 2.6114473968e16.
Formula
Step-by-Step Example
Convert 5 MeV to kilocalories:
We need to convert megaelectronvolts to kilocalories
Since 1 kcal = 2.6114473968e16 MeV, divide by 2.6114473968e16
5 ÷ 2.6114473968e16 = 1.9146470292e-16
5 MeV = 1.9146470292e-16 kcal

About These Units
Megaelectronvolt (MeV)
A megaelectronvolt (MeV) equals 1 million electronvolts. MeV measures nuclear binding energies, particle accelerator energies, and gamma radiation. The electron rest mass energy is 0.511 MeV. Nuclear reactions release energies in the MeV range.
Kilocalorie (kcal)
A kilocalorie (kcal), often written as "Calorie" (capital C) on food labels, equals 1,000 small calories or 4,184 joules. Kilocalories measure food energy. Average adult needs 2,000-2,500 kcal daily. Walking one mile burns about 80-100 kcal.
