Convert Kiloelectronvolt to Watt-hour
Type the number of kiloelectronvolts that you wish to convert to watt-hours.
How to Convert Kiloelectronvolts to Watt-hours
The kiloelectronvolt and watt-hour are both units of energy. By definition, 1 watt-hour equals exactly 2.2469432668e19 kiloelectronvolts. This means to convert kiloelectronvolts to watt-hours, you divide by 2.2469432668e19.
Formula
Step-by-Step Example
Convert 5 keV to watt-hours:
We need to convert kiloelectronvolts to watt-hours
Since 1 Wh = 2.2469432668e19 keV, divide by 2.2469432668e19
5 ÷ 2.2469432668e19 = 2.225245325e-19
5 keV = 2.225245325e-19 Wh

About These Units
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.
Watt-hour (Wh)
A watt-hour (Wh) is the energy of one watt sustained for one hour, equal to 3,600 joules. Watt-hours measure battery capacity (smartphone: 10-15 Wh, laptop: 50-100 Wh) and small appliance energy use. One Wh equals 3.6 kilojoules.
