A poundal is a unit of force in the foot–pound–second system defined as the force needed to accelerate one avoirdupois pound by one foot per second squared.

What applications use gram-force?

Gram-force is used to specify very small forces such as those in tactile switches, small springs, and precision calibration tasks.

Why convert from poundal to gram-force?

Converting from poundal to gram-force helps translate legacy FPS measurements into practical units for small forces, aiding precision tasks and modern applications.
