A poundal is a unit of force in the FPS system defined as the force that accelerates one pound mass by one foot per second squared.

Why convert poundal to pound-force?

Conversion helps translate force measurements from FPS units to more widely used US customary units for practical and engineering uses.

Does this conversion consider local gravity variations?

No, the conversion uses a fixed ratio based on standard gravity without accounting for local gravitational differences.
