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.
Ton (Assay) (Us)
The ton (assay) (US), symbolized as AT (US), is a unit of weight used primarily in the assay and precious metals industry, equivalent to 31.1034768 grams.
History/Origin
The assay ton originated in the United States as a standardized measure for precious metal content in assays, aligning with the metric system but retaining the traditional 'ton' terminology for industry consistency.
Current Use
Today, the assay ton (AT US) is used mainly in the precious metals industry for assay purposes, especially in the context of gold and silver purity measurements, and is part of weight and mass conversions within the 'Common Converters' category.
