Convert Electronvolt to Joule
1 electronvolt = 1.6021766e-19 joules (eV to J).
A electronvolt is smaller than a joule — it takes 6.24151e+18 of them to make a single joule. Both units describe energie, and the reverse is just as easy — one joule equals 6.24151e+18 electronvolts. The converter above does this in real time, and the reference chart lists the values that come up most often.
1 eV = 1.6021766e-19 J
How to convert Electronvolts to Joules
Multiply the electronvolt value by 1.60218e-19 to get joules.
Example: 10 electronvolts = 1.60218e-18 joules.
