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.
Kilogram-Force
Kilogram-force (kgf) is a unit of force defined as the force exerted by one kilogram of mass in standard gravity, approximately equal to 9.80665 newtons.
History/Origin
The kilogram-force was historically used in engineering and physics to express forces in terms of the mass unit kilogram and the acceleration due to gravity. It was more common before the widespread adoption of the newton as the standard SI unit of force.
Current Use
Kilogram-force is largely obsolete in scientific contexts and has been replaced by the newton in the International System of Units (SI). However, it may still be encountered in certain engineering fields or older documentation, especially in regions or industries that use customary units.
