209 J = 1.3045e+21 eV
Full precision:1.3045e+21 eV
Step-by-Step Solution
To convert 209 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:
209 × 6.2415e+18 = 1.3045e+21 electronvolts
So 209 joules = 1.3045e+21 electronvolts.
Quick check: 1.3045e+21 ÷ 6.2415e+18 = 209 joules
