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.
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.
