How to Convert Foot-pounds to Electronvolts
To convert foot-pounds (ft-lb) to electronvolts (eV), multiply the number of foot-pounds by 8.462 x 1018. This is because 1 foot-pound is equal to 1.35582 joules, and 1 joule is equal to approximately 6.242 x 1018 eV.
Formula
Electronvolts = Foot-pounds × (8.462 × 1018)
or
eV = ft-lb × 8.462e18
Step-by-step process
- Take the measurement in foot-pounds
- Multiply that number by 8.462e18
- The result is the equivalent energy in electronvolts
Examples
- 1 ft-lb = 1 × 8.462e18 = 8.462 x 1018 eV
- 5 ft-lb = 5 × 8.462e18 = 4.231 x 1019 eV
- 10 ft-lb = 10 × 8.462e18 = 8.462 x 1019 eV
