Frequently asked questions
What is the source unit in this conversion?
The source unit is the Watt-hour (Wh). A watt-hour is 3,600 joules.
What is the destination unit in this conversion?
The destination unit is the Electronvolt (eV). An electronvolt is the energy gained by an electron across one volt.
How do I convert Watt-hour to Electronvolt?
Multiply the Watt-hour value by 2.24694e+22. For example, 10 Wh × 2.24694e+22 = 2.24694e+23 eV.
Is the Watt-hour to Electronvolt conversion exact?
Yes. Both units belong to the same engineering measurement family (energy), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Watt-hour needs to be compared with, or reported in, Electronvolt, such as in engineering, scientific, or industrial calculations.
Can I convert Electronvolt back to Watt-hour?
Yes. Multiply the Electronvolt value by 0 to get Watt-hour.

About this conversion
This page converts Watt-hour (Wh) to Electronvolt (eV) within the engineering converter.
A watt-hour is 3,600 joules. An electronvolt is the energy gained by an electron across one volt.
The formula is eV = Wh × 2.24694e+22, based on each unit's fixed relationship to the energy base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
