Converter

Input

Result

1.60217663e-19J

J = eV × 1.60217663e-19

eV = J × 6.24150907e+18

Example: 10 eV = 10 × 1.60217663e-19 = 1.60217663e-18 J.

Express both eV and J 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 J in the base unit
$1 J = 1 J$
3
Forward conversion
$1 eV = \frac{1.60217663 \times 1 0 ^{- 19} J}{1 J} \times 1 J = \frac{1.60217663 \times 1 0 ^{- 19}}{1} J = 1.60217663 \times 1 0^{- 19} J$
4
Reverse conversion
$1 J = \frac{1 J}{1.60217663 \times 1 0 ^{- 19} J} \times 1 eV = \frac{1}{1.60217663 \times 1 0 ^{- 19}} eV = 6.24150907 \times 1 0^{18} eV$
