How the formula works
Both electronvolt and decijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 1.602176634e-18 to get decijoules. To reverse the conversion, multiply a decijoule value by 6.241509074e+17 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 Decijoule (dJ)?
A decijoule (dJ) is a metric-prefixed unit of energy equal to 10-1 joules, a fraction of a single joule, using the SI deci prefix.
How do I convert electronvolts to decijoules?
Multiply the electronvolt value by 1.602176634e-18 to get the equivalent in decijoules. For example, 5 eV × 1.602176634e-18 = 8.010883e-18 dJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.602176634e-18 is an exact, non-rounded value.
Can I convert decijoules back to electronvolts?
Yes. Divide the decijoule value by 1.602176634e-18, or multiply it by 6.241509074e+17, to get electronvolts.
