How the formula works
Both kilowatt-hour and electronvolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilowatt hours by 2.246943267e+25 to get electronvolts. To reverse the conversion, multiply a electronvolt value by 4.450490650e-26 to get back to kilowatt hours.
Frequently asked questions
What is Kilowatt-hour (kWh)?
A kilowatt-hour (kWh) is the standard billing unit for electricity, equal to 1,000 watts sustained for one hour.
What is Electronvolt (eV)?
An electronvolt (eV) is the energy gained by a single electron accelerating through a potential difference of one volt, widely used in atomic and particle physics.
How do I convert kilowatt hours to electronvolts?
Multiply the kilowatt-hour value by 2.246943267e+25 to get the equivalent in electronvolts. For example, 5 kWh × 2.246943267e+25 = 1.123472e+26 eV.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 2.246943267e+25 is an exact, non-rounded value.
Can I convert electronvolts back to kilowatt hours?
Yes. Divide the electronvolt value by 2.246943267e+25, or multiply it by 4.450490650e-26, to get kilowatt hours.
