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.
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.
