Formula: eV = thm × 6.585141e+26

Reverse: thm = eV × 1.518570e-27

Step-by-Step Example

Start with your value in Therm. For example: 5 thm
Multiply by the conversion factor: 5 x 6.585141e+26
The result is: 3.292570e+27 eV

About Therm

The therm (thm) is a unit of energy and work. One therm equals 1.055056 × 10^+8 joules. UnitConvertLab converts it against every other energy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: energy calculations, engineering and science, education.

About Electron Volt

The electron volt (eV) is a unit of energy and work. One electron volt equals 1.602177 × 10^-19 joules. UnitConvertLab converts it against every other energy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: energy calculations, engineering and science, education.
