Various FPS units of force which have specific names are as follows:
Poundal
The poundal is an FPS unit of force.
It is defined as being:
- The amount of force required to accelerate a mass of one pound at a rate of one foot per second squared.

\(\ds \) | \(\approx\) | \(\ds 0 \cdotp 13825 \, 5\) | newtons |
Pound Force
The pound force is a FPS unit of force.
It is defined as being:
- The gravitational force exerted on a mass of one avoirdupois pound on the surface of Earth.
In this context, the value of the standard acceleration due to gravity is used, taken to be $32.17404 \, 9 \, \mathrm {ft} \, \mathrm s^{-2}$.

Ton Force
The ton force is a FPS unit of force.
It is defined as being:
- The gravitational force exerted on a mass of one ton on the surface of Earth.
In this context, the value of the standard acceleration due to gravity is used, taken to be $32.174049 \, \mathrm {ft} \, \mathrm s^{-2}$.
