How to convert electronvolts to megajoules
There are 6.241509 × 10²⁴ electronvolts in one megajoule, so divide the number of electronvolts by 6.241509 × 10²⁴.
MJ = eV ÷ 6.241509 × 10²⁴
1 eV = 1.602177 × 10⁻²⁵ MJ · 1 MJ = 6.241509 × 10²⁴ eV
Worked example
To convert 5 electronvolts to megajoules: 5 eV ÷ 6.241509 × 10²⁴ = 8.010883 × 10⁻²⁵ MJ.
