20 eV = 3.2044e-18 J
Full precision:3.2044e-18 J
Step-by-Step Solution
To convert 20 electronvolts to joules, we divide by 6.2415e+18 because one joule equals exactly 6.2415e+18 electronvolts.
1 joule = 6.2415e+18 electronvolts
Since there are 6.2415e+18 electronvolts in every joule, we divide our value by this factor:
20 ÷ 6.2415e+18 = 3.2044e-18 joules
So 20 electronvolts = 3.2044e-18 joules.
Quick check: 3.2044e-18 × 6.2415e+18 = 20 electronvolts
