How to Convert Gigajoules to Kiloelectronvolts
The gigajoule and kiloelectronvolt are both units of energy. By definition, 1 gigajoule equals exactly 6.2415090745e24 kiloelectronvolts. This means to convert gigajoules to kiloelectronvolts, you multiply by 6.2415090745e24.
Formula
Step-by-Step Example
Convert 5 GJ to kiloelectronvolts:
We need to convert gigajoules to kiloelectronvolts
Since 1 GJ = 6.2415090745e24 keV, multiply by 6.2415090745e24
5 × 6.2415090745e24 = 3.1207545372e25
5 GJ = 3.1207545372e25 keV

About These Units
Gigajoule (GJ)
A gigajoule (GJ) equals 1 billion joules or approximately 277.8 kilowatt-hours. Gigajoules measure natural gas billing, industrial energy use, and building energy consumption. One GJ equals about 26.8 cubic meters of natural gas.
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.
