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 Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
How to convert electronvolts to feet-pounds
1 electronvolt is equal to 1.18170484e-19 feet-pound when both are expressed in joule-equivalents:
1 ev = (1.602176634e-19 J ÷ 1.3558179483314003 J) ftlb = 1.18170484e-19 ftlb
Each electronvolt is defined as 1.602176634e-19 J and each feet-pound as 1.3558179483314003 J in this tool, so one ev equals 1.602176634e-19 ÷ 1.3558179483314003 ftlb = 1.18170484e-19 ftlb.
Let d(ev) be the numeric amount in Electronvolt (ev), and d(ftlb) the amount in Feet-Pound (ftlb). Then:
d(ftlb) = d(ev) × (1.602176634e-19 / 1.3558179483314003)
Equivalently, divide by how many ev fit into one ftlb (joules per ftlb divided by joules per ev):
d(ftlb) = d(ev) ÷ 8.46235003e+18
Or: feet-pound = electronvolt ÷ 8.46235003e+18
Examples
Example #1: Convert 1 ev to feet-pound
1 ev = 1 ev × (1.602176634e-19/1.3558179483314003) ftlb = 0 ftlb
1 ev = 1 ev ÷ 8.46235003e+18 = 0 ftlb
Example #2: Convert 10 ev to feet-pound
10 ev = 10 ev × (1.602176634e-19/1.3558179483314003) ftlb = 0 ftlb
10 ev = 10 ev ÷ 8.46235003e+18 = 0 ftlb
Summary
To convert Electronvolt to Feet-Pound, multiply the value in ev by the ratio of joules per ev divided by joules per ftlb. Equivalently: value_ftlb = value_ev × (1.602176634e-19 / 1.3558179483314003). Numerically, 1 ev equals 1.1817048416948545e-19 ftlb.
Relationship context
You are converting between atomic-scale energy (electronvolts) (Electronvolts) and US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds). All values are mapped through joules first. The numeric factor is 1.181705e-19.
