How the formula works
Both electronvolt and quectojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 160217663400 to get quectojoules. To reverse the conversion, multiply a quectojoule value by 6.241509074e-12 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 Quectojoule (qJ)?
A quectojoule (qJ) is a metric-prefixed unit of energy equal to 10-30 joules, a fraction of a single joule, using the SI quecto prefix.
How do I convert electronvolts to quectojoules?
Multiply the electronvolt value by 160217663400 to get the equivalent in quectojoules. For example, 5 eV × 160217663400 = 8.010883e+11 qJ.
Is this conversion exact?
