TeraeV

TeraeV is a nonstandard unit of energy sometimes used in discussions of high-energy physics and science fiction. In conventional physics literature, the energy unit commonly employed is the tera-electronvolt, abbreviated TeV. The two terms are effectively equivalent, since one teraelectronvolt equals 10^12 electronvolts; by extension, 1 TeraeV = 1 TeV.

Etymology and usage: The form TeraeV combines the SI prefix tera- (10^12) with the electronvolt (eV). The capitalization varies by author, and there is no formal SI endorsement for "TeraeV." In professional contexts, TeV remains the standard notation. TeraeV appears mainly in popular science writing, speculative scenarios, or as a didactic shorthand.

Conversions: 1 eV = 1.602176634×10^-19 J, so 1 TeV = 1e12 eV ≈ 1.602176634×10^-7 J. Therefore, 1 TeraeV ≈ 1.602176634×10^-7 J, the same as 1 TeV.

Notes: Energies in high-energy physics are typically quoted in TeV when referring to particle accelerators, collision energies, and particle masses. The term TeraeV is thus largely historical or stylistic rather than a separate unit of measure.
