Type the number of kilocalories that you wish to convert to kiloelectronvolts.
How to Convert Kilocalories to Kiloelectronvolts
The kilocalorie and kiloelectronvolt are both units of energy. By definition, 1 kilocalorie equals exactly 2.6114473968e19 kiloelectronvolts. This means to convert kilocalories to kiloelectronvolts, you multiply by 2.6114473968e19.
Formula
Step-by-Step Example
Convert 5 kcal to kiloelectronvolts:
We need to convert kilocalories to kiloelectronvolts
Since 1 kcal = 2.6114473968e19 keV, multiply by 2.6114473968e19
5 × 2.6114473968e19 = 1.3057236984e20
5 kcal = 1.3057236984e20 keV

About These Units
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.
Kiloelectronvolt (keV)
A kiloelectronvolt (keV) equals 1,000 electronvolts. KeV measures X-ray energy (medical X-rays: 20-150 keV), electron microscope beam energy, and radiation dosimetry. Gamma rays from nuclear decay often have energies in keV to MeV range.
