Scruple (Apothecary)
A scruple (s.ap) is an old unit of weight used in apothecary measurements, equivalent to 1.3 grains or approximately 1.3 grams.
History/Origin
The scruple originated in ancient Greece and was adopted into Roman and medieval European apothecary systems. It was historically used for measuring small quantities of medicinal substances and drugs.
Current Use
Today, the scruple is largely obsolete and replaced by metric units, but it is still referenced in historical contexts and traditional apothecary practices.
Poundal
The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system, defined as the force required to accelerate a one-pound mass at a rate of one foot per second squared.
History/Origin
The poundal was introduced in the 19th century as part of the FPS system of units, primarily used in engineering and physics before the widespread adoption of the SI system. It was designed to provide a consistent force unit based on imperial units.
Current Use
Today, the poundal is largely obsolete and rarely used outside of historical or specialized engineering contexts. It is mainly referenced for educational purposes or in discussions of imperial units, with the SI unit of force (newton) being the standard.
