About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
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 feet-pounds to electronvolts
1 feet-pound is equal to 8.46235003e+18 electronvolt when both are expressed in joule-equivalents:
1 ftlb = (1.3558179483314003 J ÷ 1.602176634e-19 J) ev = 8.46235003e+18 ev
Each feet-pound is defined as 1.3558179483314003 J and each electronvolt as 1.602176634e-19 J in this tool, so one ftlb equals 1.3558179483314003 ÷ 1.602176634e-19 ev = 8.46235003e+18 ev.
Let d(ftlb) be the numeric amount in Feet-Pound (ftlb), and d(ev) the amount in Electronvolt (ev). Then:
d(ev) = d(ftlb) × (1.3558179483314003 / 1.602176634e-19)
Equivalently, divide by how many ftlb fit into one ev (joules per ev divided by joules per ftlb):
d(ev) = d(ftlb) ÷ 1.18170484e-19
Or: electronvolt = feet-pound ÷ 1.18170484e-19
Examples
Example #1: Convert 1 ftlb to electronvolt
1 ftlb = 1 ftlb × (1.3558179483314003/1.602176634e-19) ev = 8462350027829999616 ev
1 ftlb = 1 ftlb ÷ 1.18170484e-19 = 8462350027829999616 ev
Example #2: Convert 10 ftlb to electronvolt
10 ftlb = 10 ftlb × (1.3558179483314003/1.602176634e-19) ev = 84623500278300000256 ev
10 ftlb = 10 ftlb ÷ 1.18170484e-19 = 84623500278300000256 ev
Summary
To convert Feet-Pound to Electronvolt, multiply the value in ftlb by the ratio of joules per ftlb divided by joules per ev. Equivalently: value_ev = value_ftlb × (1.3558179483314003 / 1.602176634e-19). Numerically, 1 ftlb equals 8462350027827209000 ev.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds) and atomic-scale energy (electronvolts) (Electronvolts). All values are mapped through joules first. The numeric factor is 8.462350e+18.
