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 torr (Torr). A torr is 1/760 standard atmosphere.
How do I convert electronvolt to torr?
Multiply the electronvolt value by 1.201731e-21. For example, 10 eV × 1.201731e-21 = 1.201731e-20 Torr.
Is the electronvolt to torr 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, torr, such as in engineering, scientific, or laboratory calculations.
Can I convert torr back to electronvolt?
Yes. Multiply the torr value by 8.321328e+20 to get electronvolt.

About this conversion
This page converts electronvolt (eV) to torr (Torr) within the scientific units converter.
An electronvolt is the energy gained by an electron across one volt.
A torr is 1/760 standard atmosphere.
The formula is torr = electronvolt × 1.201731e-21, 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.
