How to Convert Electronvolts to Foot-pounds
The electronvolt and foot-pound are both units of energy. By definition, 1 foot-pound equals exactly 8.4623500276e18 electronvolts. This means to convert electronvolts to foot-pounds, you divide by 8.4623500276e18.
Formula
Step-by-Step Example
Convert 5 eV to foot-pounds:
We need to convert electronvolts to foot-pounds
Since 1 ft·lb = 8.4623500276e18 eV, divide by 8.4623500276e18
5 ÷ 8.4623500276e18 = 5.9085242086e-19
5 eV = 5.9085242086e-19 ft·lb

About These Units
Electronvolt (eV)
An electronvolt (eV) is the energy gained by an electron accelerated through 1 volt potential difference, equal to 1.602×10⁻¹⁹ joules. Electronvolts measure atomic and molecular energies, photon energy (visible light: 1.6-3.3 eV), and particle physics. X-rays range from 100 eV to 100 keV.
Foot-pound (ft·lb)
A foot-pound (ft·lb or ft-lbf) is the energy to raise 1 pound by 1 foot against gravity, equal to 1.356 joules. Foot-pounds measure torque, bullet energy (muzzle energy: 300-4,000 ft·lb), and mechanical work in US engineering. One ft·lb equals 0.324 calories.
