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 hertz (Hz). The hertz is one cycle per second.
How do I convert electronvolt to hertz?
Multiply the electronvolt value by 1.602177e-19. For example, 10 eV × 1.602177e-19 = 1.602177e-18 Hz.
Is the electronvolt to hertz conversion exact?
Yes. The relationship between these units is a fixed mathematical or SI-defined ratio, so the conversion factor is exact 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, hertz, such as in engineering, scientific, or laboratory calculations.
Can I convert hertz back to electronvolt?
Yes. Multiply the hertz value by 6.241509e+18 to get electronvolt.

About this conversion
This page converts electronvolt (eV) to hertz (Hz) within the scientific units converter.
An electronvolt is the energy gained by an electron across one volt.
The hertz is one cycle per second.
The formula is hertz = electronvolt × 1.602177e-19, based on each unit's fixed relationship to the scientific converter's reference units.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
Use the calculator above for instant results, or the table below for common electronvolt values already converted to hertz.
