About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
About Electronvolt
The electronvolt is the energy change of one elementary charge across 1 V: 1 eV ≈ 1.602176634×10⁻¹⁹ J (exact by SI definition). Used in particle physics and chemistry.
How to convert therm to electronvolts
1 therm is equal to 6.58514068e+26 electronvolt when both are expressed in joule-equivalents:
1 therm = (105,505,585.262 J ÷ 1.602176634e-19 J) ev = 6.58514068e+26 ev
Each therm is defined as 105,505,585.262 J and each electronvolt as 1.602176634e-19 J in this tool, so one therm equals 105,505,585.262 ÷ 1.602176634e-19 ev = 6.58514068e+26 ev.
Let d(therm) be the numeric amount in Therm (therm), and d(ev) the amount in Electronvolt (ev). Then:
d(ev) = d(therm) × (105,505,585.262 / 1.602176634e-19)
Equivalently, divide by how many therm fit into one ev (joules per ev divided by joules per therm):
d(ev) = d(therm) ÷ 1.51857044e-27
Or: electronvolt = therm ÷ 1.51857044e-27
Examples
Example #1: Convert 1 therm to electronvolt
1 therm = 1 therm × (105,505,585.262/1.602176634e-19) ev = 6.58514067819e+26 ev
1 therm = 1 therm ÷ 1.51857044e-27 = 6.58514067819e+26 ev
Example #2: Convert 10 therm to electronvolt
10 therm = 10 therm × (105,505,585.262/1.602176634e-19) ev = 6.58514067819e+27 ev
10 therm = 10 therm ÷ 1.51857044e-27 = 6.58514067819e+27 ev
Summary
To convert Therm to Electronvolt, multiply the value in therm by the ratio of joules per therm divided by joules per ev. Equivalently: value_ev = value_therm × (105505585.262 / 1.602176634e-19). Numerically, 1 therm equals 6.585140678190667e+26 ev.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Therm) and atomic-scale energy (electronvolts) (Electronvolts). All values are mapped through joules first. The numeric factor is 6.585141e+26.
