Direct answer

1 eV = 1.60217663e-22 kJ

kJ = eV × 1.60217663e-22

Converter

Input

Result

1.60217663e-22kJ

kJ = eV × 1.60217663e-22

eV = kJ × 6.24150907e+21

Example: 10 eV = 10 × 1.60217663e-22 = 1.60217663e-21 kJ.

Express both eV and kJ in the same base unit J (joule), then cancel the shared base unit.

1
Rewrite eV in the base unit
$1 eV = 1.60217663 \times 1 0^{- 19} J$
2
Rewrite kJ in the base unit
$1 kJ = 1, 000 J$
3
Forward conversion
$1 eV = \frac{1.60217663 \times 1 0 ^{- 19} J}{1 , 000 J} \times 1 kJ = \frac{1.60217663 \times 1 0 ^{- 19}}{1 , 000} kJ = 1.60217663 \times 1 0^{- 22} kJ$
4
Reverse conversion
$1 kJ = \frac{1 , 000 J}{1.60217663 \times 1 0 ^{- 19} J} \times 1 eV = \frac{1 , 000}{1.60217663 \times 1 0 ^{- 19}} eV = 6.24150907 \times 1 0^{21} eV$
