How the formula works
Both electronvolt and us therm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 1.518933028e-27 to get therms. To reverse the conversion, multiply a us therm value by 6.583568738e+26 to get back to electronvolts.
Frequently asked questions
What is Electronvolt (eV)?
An electronvolt (eV) is the energy gained by a single electron accelerating through a potential difference of one volt, widely used in atomic and particle physics.
What is US therm (therm)?
The US therm is a natural-gas billing unit equal to 100,000 BTU, used by utilities to measure gas usage.
How do I convert electronvolts to therms?
Multiply the electronvolt value by 1.518933028e-27 to get the equivalent in therms. For example, 5 eV × 1.518933028e-27 = 7.594665e-27 therm.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.518933028e-27 is an exact, non-rounded value.
Can I convert therms back to electronvolts?
Yes. Divide the us therm value by 1.518933028e-27, or multiply it by 6.583568738e+26, to get electronvolts.
