2 J = 1.2483e+19 eV
Full precision:1.2483e+19 eV
Step-by-Step Solution
To convert 2 joules to electronvolts, we multiply by 6.2415e+18 because one joule equals exactly 6.2415e+18 electronvolts.
1 joule = 6.2415e+18 electronvolts
Since each joule contains 6.2415e+18 electronvolts, we multiply our value by this factor:
2 × 6.2415e+18 = 1.2483e+19 electronvolts
So 2 joules = 1.2483e+19 electronvolts.
Quick check: 1.2483e+19 ÷ 6.2415e+18 = 2 joules
