How the formula works
Both electronvolt and terajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 1.602176634e-31 to get terajoules. To reverse the conversion, multiply a terajoule value by 6.241509074e+30 to get back to electronvolts.
Frequently asked questions
What is Electronvolt (eV)?
An electronvolt (eV) is the energy gained by a single electron accelerating through a potential difference of one volt, widely used in atomic and particle physics.
What is Terajoule (TJ)?
A terajoule (TJ) is a metric-prefixed unit of energy equal to 1012 joules, using the SI tera prefix.
How do I convert electronvolts to terajoules?
Multiply the electronvolt value by 1.602176634e-31 to get the equivalent in terajoules. For example, 5 eV × 1.602176634e-31 = 8.010883e-31 TJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.602176634e-31 is an exact, non-rounded value.
Can I convert terajoules back to electronvolts?
Yes. Divide the terajoule value by 1.602176634e-31, or multiply it by 6.241509074e+30, to get electronvolts.
