Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
Quarter (Uk)
A quarter (qr) is a traditional unit of weight used in the UK, typically equal to one-quarter of a hundredweight, or 28 pounds (approximately 12.7 kilograms).
History/Origin
The quarter has historical roots in British measurement systems, originating from the need to divide larger weights into manageable parts. It was commonly used in trade and agriculture before the adoption of the metric system.
Current Use
Today, the quarter is largely obsolete in official measurement but may still be used informally in certain industries such as agriculture and livestock to denote weight, especially in the UK.
