Convert Gigajoule to Kiloelectronvolt

Type the number of gigajoules that you wish to convert to kiloelectronvolts.

1 GJ (gigajoules) = 6.2415090745e24 keV (kiloelectronvolts)

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

kiloelectronvolts = gigajoules × 6.2415090745e24

Step-by-Step Example

Convert 5 GJ to kiloelectronvolts:

1
Convert 5 GJ to kiloelectronvolts

We need to convert gigajoules to kiloelectronvolts

2
Apply the formula

Since 1 GJ = 6.2415090745e24 keV, multiply by 6.2415090745e24

5 × 6.2415090745e24 = 3.1207545372e25

Answer

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.
