Frequently asked questions
What is the source unit in this conversion?
The source unit is the Electronvolt (eV). An electronvolt is the energy gained by an electron across one volt.
What is the destination unit in this conversion?
The destination unit is the Femtojoule (fJ). Femtojoule is 1e-15 joule units.
How do I convert Electronvolt to Femtojoule?
Multiply the Electronvolt value by 0.000160218. For example, 10 eV × 0.000160218 = 0.00160218 fJ.
Is the Electronvolt to Femtojoule 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 Electronvolt needs to be compared with, or reported in, Femtojoule, such as in engineering, scientific, or industrial calculations.
Can I convert Femtojoule back to Electronvolt?
Yes. Multiply the Femtojoule value by 6241.51 to get Electronvolt.

About this conversion
This page converts Electronvolt (eV) to Femtojoule (fJ) within the engineering converter.
An electronvolt is the energy gained by an electron across one volt. Femtojoule is 1e-15 joule units.
The formula is fJ = eV × 0.000160218, 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.
