Attonewton [aN]
Attonewton is an extraordinarily small unit of force in the International System of Units (SI).
1 attonewton (aN) equals 10โ18 newtons (0.000000000000000001 newton).
It is used in highly specialized fields such as quantum physics, nanotechnology, and advanced experimental research where forces are incredibly minute.
To put it in perspective:
1 aN=0.000000000000000001 N
Attonewtons allow scientists to quantify forces at the tiniest scales imaginable, beyond typical atomic interactions.
Pond [p]
The pond is a historical unit of force, equivalent to the force exerted by gravity on a mass of one gram.
1 pond=1 gramร9.80665 m/s2=0.00980665 newtons
In other words, 1 pond is approximately 0.00981 newtons.
The pond is rarely used today, having been replaced by the newton, but it may still appear in older scientific literature or certain niche applications.
It is similar in concept to the gram-force (gf).
