Stone (Us)
A stone (st) is a unit of weight primarily used in the United States, equal to 14 pounds or approximately 6.35 kilograms.
History/Origin
The stone has origins in medieval England, where it was used as a convenient weight measure for trade and commerce. Its value varied regionally before standardization, and it has been used historically for measuring human body weight and other goods.
Current Use
Today, the stone is mainly used in the UK and Ireland for body weight measurement, while in the United States, it is rarely used and often replaced by pounds or kilograms in most contexts.
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.
