Convert Electronvolt to Kilowatt-hour
Input the number of electronvolts you want to convert to kilowatt-hours.
How to Convert Electronvolts to Kilowatt-hours
The electronvolt and kilowatt-hour are both units of energy. By definition, 1 kilowatt-hour equals exactly 2.2469432668e25 electronvolts. This means to convert electronvolts to kilowatt-hours, you divide by 2.2469432668e25.
Formula
Step-by-Step Example
Convert 5 eV to kilowatt-hours:
We need to convert electronvolts to kilowatt-hours
Since 1 kWh = 2.2469432668e25 eV, divide by 2.2469432668e25
5 ÷ 2.2469432668e25 = 2.225245325e-25
5 eV = 2.225245325e-25 kWh

About These Units
Electronvolt (eV)
An electronvolt (eV) is the energy gained by an electron accelerated through 1 volt potential difference, equal to 1.602×10⁻¹⁹ joules. Electronvolts measure atomic and molecular energies, photon energy (visible light: 1.6-3.3 eV), and particle physics. X-rays range from 100 eV to 100 keV.
Kilowatt-hour (kWh)
A kilowatt-hour (kWh) is the standard unit for electricity billing, equal to 1,000 watt-hours or 3.6 megajoules. Average US home uses 900 kWh monthly. Running a 100W bulb for 10 hours uses 1 kWh. Electricity costs $0.10-0.30 per kWh typically.
