What is the scruple (apothecary) unit?

The scruple (apothecary) is a historical unit of mass used mainly in pharmacy and medicine, equal to 20 grains or about 1.296 grams.

What does the poundal measure?

The poundal is a unit of force in the foot–pound–second system, representing the force that accelerates a one pound mass at one foot per second squared.

Can I directly convert scruples to poundals?

Since scruple is a mass unit and poundal is a force unit, direct conversion assumes a context involving acceleration, such as gravity, to relate mass to force.
