Convert Kilojoule to Electronvolt
1 kilojoule = 6.2415091e+21 electronvolts (kJ to eV).
A kilojoule is larger than a electronvolt — one kilojoule contains 6.24151e+21 electronvolts. Both units describe energie, and the reverse is just as easy — one electronvolt equals 1.60218e-22 kilojoules. The converter above does this in real time, and the reference chart lists the values that come up most often.
