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.
Stone (Uk)
A stone (st) is a British unit of weight equal to 14 pounds avoirdupois, primarily used for measuring body weight.
History/Origin
The stone has origins in medieval England, where it was used as a practical unit of weight for trade and commerce. Its use has persisted in the UK for measuring human body weight, despite the metric system's adoption elsewhere.
Current Use
Today, the stone is still commonly used in the UK and Ireland for personal weight measurement, especially in the context of health and fitness, although it is largely replaced by kilograms in official and international contexts.
