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.
About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
How to convert electronvolts to therm
1 electronvolt is equal to 1.51857044e-27 therm when both are expressed in joule-equivalents:
1 ev = (1.602176634e-19 J ÷ 105,505,585.262 J) therm = 1.51857044e-27 therm
Each electronvolt is defined as 1.602176634e-19 J and each therm as 105,505,585.262 J in this tool, so one ev equals 1.602176634e-19 ÷ 105,505,585.262 therm = 1.51857044e-27 therm.
Let d(ev) be the numeric amount in Electronvolt (ev), and d(therm) the amount in Therm (therm). Then:
d(therm) = d(ev) × (1.602176634e-19 / 105,505,585.262)
Equivalently, divide by how many ev fit into one therm (joules per therm divided by joules per ev):
d(therm) = d(ev) ÷ 6.58514068e+26
Or: therm = electronvolt ÷ 6.58514068e+26
Examples
Example #1: Convert 1 ev to therm
1 ev = 1 ev × (1.602176634e-19/105,505,585.262) therm = 0 therm
1 ev = 1 ev ÷ 6.58514068e+26 = 0 therm
Example #2: Convert 10 ev to therm
10 ev = 10 ev × (1.602176634e-19/105,505,585.262) therm = 0 therm
10 ev = 10 ev ÷ 6.58514068e+26 = 0 therm
Summary
To convert Electronvolt to Therm, multiply the value in ev by the ratio of joules per ev divided by joules per therm. Equivalently: value_therm = value_ev × (1.602176634e-19 / 105505585.262). Numerically, 1 ev equals 1.5185704434711635e-27 therm.
Relationship context
You are converting between atomic-scale energy (electronvolts) (Electronvolts) and US / imperial engineering units (BTU, therm, ft·lb) (Therm). All values are mapped through joules first. The numeric factor is 1.518570e-27.
