7.2e-19 J = 4.4939 eV
Full precision:4.4939 eV
Step-by-Step Solution
To convert 7.2e-19 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:
7.2e-19 × 6.2415e+18 = 4.4939 electronvolts
So 7.2e-19 joules = 4.4939 electronvolts.
Quick check: 4.4939 ÷ 6.2415e+18 = 7.2e-19 joules
