Poundal [pdl]

The poundal is a unit of force in the foot-pound-second (FPS) system, mainly used in the United States.

It is defined as the force required to accelerate a one-pound mass by one foot per second squared.
Mathematically:

1 \text{ pdl} = 1 \text{ lb} \times 1 \text{ ft/s}^2 = 0.138255 \text{ newtons}

The poundal is smaller than the pound-force since Earth's gravity accelerates a pound mass at approximately 32.174 ft/s², making:

1 \text{ lbf} = 32.174 \text{ pdl}

It is mostly of historical interest and rarely used in modern engineering but can appear in classical mechanics problems using the FPS system.

Femtonewton [fN]

Femtonewton is an ultra-small unit of force in the International System of Units (SI).

1 femtonewton (fN) equals $10^{-15}$ newtons (0.000000000000001 newton).
It is used in cutting-edge research fields like atomic physics, nanotechnology, and quantum mechanics to measure incredibly tiny forces.
To put it in perspective:

1 \text{ fN} = 0.000000000000001 \text{ N}

Femtonewtons enable precise measurement of forces at atomic and subatomic levels where minute interactions occur.
