How the formula works
Both electronvolt and decajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 1.602176634e-20 to get decajoules. To reverse the conversion, multiply a decajoule value by 6.241509074e+19 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 Decajoule (daJ)?
A decajoule (daJ) is a metric-prefixed unit of energy equal to 101 joules, using the SI deca prefix.
How do I convert electronvolts to decajoules?
Multiply the electronvolt value by 1.602176634e-20 to get the equivalent in decajoules. For example, 5 eV × 1.602176634e-20 = 8.010883e-20 daJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.602176634e-20 is an exact, non-rounded value.
Can I convert decajoules back to electronvolts?
Yes. Divide the decajoule value by 1.602176634e-20, or multiply it by 6.241509074e+19, to get electronvolts.
