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 British Thermal Unit
The British thermal unit used here is the IT BTU: ≈ 1,055.056 J. It appears in HVAC, heating equipment, and US engineering data.
How to convert electronvolts to british thermal units
1 electronvolt is equal to 1.51857044e-22 british thermal unit when both are expressed in joule-equivalents:
1 ev = (1.602176634e-19 J ÷ 1,055.05585262 J) btu = 1.51857044e-22 btu
Each electronvolt is defined as 1.602176634e-19 J and each british thermal unit as 1,055.05585262 J in this tool, so one ev equals 1.602176634e-19 ÷ 1,055.05585262 btu = 1.51857044e-22 btu.
Let d(ev) be the numeric amount in Electronvolt (ev), and d(btu) the amount in British Thermal Unit (btu). Then:
d(btu) = d(ev) × (1.602176634e-19 / 1,055.05585262)
Equivalently, divide by how many ev fit into one btu (joules per btu divided by joules per ev):
d(btu) = d(ev) ÷ 6.58514068e+21
Or: british thermal unit = electronvolt ÷ 6.58514068e+21
Examples
Example #1: Convert 1 ev to british thermal unit
1 ev = 1 ev × (1.602176634e-19/1,055.05585262) btu = 0 btu
1 ev = 1 ev ÷ 6.58514068e+21 = 0 btu
Example #2: Convert 10 ev to british thermal unit
10 ev = 10 ev × (1.602176634e-19/1,055.05585262) btu = 0 btu
10 ev = 10 ev ÷ 6.58514068e+21 = 0 btu
Summary
To convert Electronvolt to British Thermal Unit, multiply the value in ev by the ratio of joules per ev divided by joules per btu. Equivalently: value_btu = value_ev × (1.602176634e-19 / 1055.05585262). Numerically, 1 ev equals 1.5185704434711636e-22 btu.
Relationship context
You are converting between atomic-scale energy (electronvolts) (Electronvolts) and US / imperial engineering units (BTU, therm, ft·lb) (British Thermal Units). All values are mapped through joules first. The numeric factor is 1.518570e-22.
