Ounce (oz)
Definition: The ounce (oz) is a unit of weight in the avoirdupois system, where one ounce is defined as 1/16th of a pound, or approximately 28.3495 grams. It is used for measuring small weights, particularly in food, jewelry, and postal services.
History: The ounce originates from the Roman uncia, which was 1/12 of a libra (pound). The system evolved in medieval England, leading to the modern avoirdupois system in 16th-century Britain, where 16 ounces make up one pound. Despite metrication, the ounce remains in widespread use in some countries.
Current Use: Ounces are commonly used for food packaging, precious metals (like gold and silver in troy ounces), and postal weights. They also appear in personal weight measurement and recipes, especially in countries that use the imperial system.
UK Long Ton
Definition: The UK long ton, also called the imperial ton, equals 2,240 pounds or approximately 1,016 kilograms. It was widely used in British commerce and shipping before the UK adopted the metric system.
History: The long ton dates back to medieval England, where various ton weights were used for measuring bulk goods. It was standardized in the 19th century under the British Weights and Measures Act. Although largely replaced by metric units in the UK, it remained influential in naval and international trade for centuries.
Current Use: The UK long ton is mostly obsolete but still appears in maritime freight and historical records. It is occasionally used in industries where British imperial measurements were historically significant, such as shipbuilding and military logistics.
