Gram-Force [gf]

The gram-force (gf) is a unit of force based on the force exerted by one gram of mass under standard gravity.

It is defined as the force exerted by a mass of 1 gram under the acceleration due to gravity (9.80665 m/s²).
Mathematically:

1 \text{ gf} = 1 \text{ g} \times 9.80665 \text{ m/s}^2 = 9.80665 \times 10^{-3} \text{ N} = 0.00980665 \text{ N}

Although not an SI unit, gram-force is used in some fields like engineering and material science for small force measurements.

Example: The force due to a 500 g mass is 500 gf, which is approximately 4.9 newtons.

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.
