How the formula works
Both decajoule and electronvolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decajoules by 6.241509074e+19 to get electronvolts. To reverse the conversion, multiply a electronvolt value by 1.602176634e-20 to get back to decajoules.
Frequently asked questions
What is Decajoule (daJ)?
A decajoule (daJ) is a metric-prefixed unit of energy equal to 101 joules, using the SI deca prefix.
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.
How do I convert decajoules to electronvolts?
Multiply the decajoule value by 6.241509074e+19 to get the equivalent in electronvolts. For example, 5 daJ × 6.241509074e+19 = 3.120755e+20 eV.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 6.241509074e+19 is an exact, non-rounded value.
Can I convert electronvolts back to decajoules?
Yes. Divide the electronvolt value by 6.241509074e+19, or multiply it by 1.602176634e-20, to get decajoules.
