20 eV = 7.6586e-22 kcal
Full precision:7.6586e-22 kcal
Step-by-Step Solution
To convert 20 electronvolts to kilocalories, we divide by 2.6114e+22 because one kilocalorie equals exactly 2.6114e+22 electronvolts.
1 kilocalorie = 2.6114e+22 electronvolts
Since there are 2.6114e+22 electronvolts in every kilocalorie, we divide our value by this factor:
20 ÷ 2.6114e+22 = 7.6586e-22 kilocalories
So 20 electronvolts = 7.6586e-22 kilocalories.
Quick check: 7.6586e-22 × 2.6114e+22 = 20 electronvolts
