2eVh
2eVh is not a standard unit or widely recognized constant in physics. Its meaning depends on the context in which it appears, and it can be encountered as a shorthand, a label in a dataset, or as a nonstandard product of other quantities. Because it is not unambiguously defined, readers should rely on surrounding text to interpret its intended meaning.
One possible interpretation is that 2eVh represents the product of an energy scale of 2 electronvolts (2
In other contexts, 2eVh might appear as a label or shorthand in notes or datasets, indicating a
When encountering ambiguous notation like 2eVh, standard practice is to convert energies to conventional units and,
