Convert pound-force to femtonewton
Please provide values below to convert pound-force [lbf] to femtonewton [fN], or Convert femtonewton to pound-force.
1 lbf = 4.4482e+15 fN. To convert pound-force to femtonewton, multiply the value by 4.4482e+15; to go the other way, divide by it (1 fN = 2.2481e-16 lbf). Both units measure force and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 lbf = 4.4482e+15 fN
- 1 fN = 2.2481e-16 lbf
- 10 lbf = 4.4482e+16 fN
- 100 lbf = 4.4482e+17 fN
How to Convert Pound-Force to Femtonewton

Pound-Force
Pound-force (lbf) is a unit of force in the imperial system, defined as the force required to accelerate a one-pound mass at a rate of 32.174 feet per second squared.
History/Origin
The pound-force originated from the British Imperial system and has been used historically in engineering and physics to quantify force, especially in the United States and the UK, before the widespread adoption of the SI system.
Current Use
Today, pound-force is primarily used in the United States and some other countries for engineering, manufacturing, and mechanical applications where imperial units are still prevalent, often in contexts like specifying engine torque or structural loads.
Femtonewton
A femtonewton (fN) is a unit of force equal to 10^-15 newtons.
History/Origin
The femtonewton is part of the metric system's SI prefixes, introduced to measure extremely small forces, particularly in scientific and engineering contexts involving micro- or nano-scale phenomena.
Current Use
Femtonewtons are used in fields such as nanotechnology, molecular physics, and precision measurements where forces at the femtonewton scale are relevant.
