About these units
Ounce (oz)
The ounce is a unit equal to 1/16 of a pound, or approximately 28.3495 grams, with roots in ancient Roman "uncia"—one-twelfth of a pound. The ounce is used for measuring small masses in cooking, postal services, gemstones (troy ounces), and various consumer goods. Despite not being part of the metric system, the ounce remains a staple in US everyday life, from food packaging to hardware components. Its small size gives it a practical niche where grams might feel too unfamiliar for some audiences. Multiple ounce variants exist historically—avoirdupois, troy, apothecary—but the avoirdupois ounce is now the standard in general commerce. Its endurance reflects the cultural weight of imperial units and the long history of Western measurement systems.
UK Ton (Long) (ton (UK))
The British long ton equals 2,240 pounds (1,016.0469088 kilograms). Historically used throughout the British Empire, it appears frequently in naval records, early engineering documents, and historical trade ledgers. The long ton's relation to the imperial hundredweight (112 pounds × 20) makes sense within the structure of older English measurement systems. Although replaced by metric tons in the UK, it persists in maritime contexts and in interpreting historical documents. Its presence captures the complexity of pre-metric trade and the need for careful interpretation when comparing international tonnage systems.
