What does pound foot per square second represent?

It is a force unit in the foot–pound–second system representing the force to accelerate one pound mass at one foot per second squared, also known as the poundal.

Why convert pound foot/square second to decinewton?

To express legacy FPS force values in a modern SI-derived unit suited for measuring relatively small forces in engineering, laboratory, or educational settings.

Is decinewton an official SI unit?

No, the decinewton is an SI-derived unit but not an official SI base unit; it is used mainly for convenience in fractional newton measurements.
