Ounce
Definition: An ounce (symbol: oz) is a unit of mass in the imperial and US customary systems of measurement. The avoirdupois ounce (the common ounce) is defined as exactly 28.349523125 grams and is equivalent to one sixteenth of an avoirdupois pound.
History/origin: The origin of the term ounce stems from the Roman uncia, which means a "twelfth part," and the use of a standardized copper bar which defined both the Roman pound and foot. The copper bar was divided into twelve equal parts, called unciae. This relationship between the Roman pound and foot eventually contributed to the uncia being the basis of the modern inch as well as the common ounce. The ounce has been used as a standard of mass throughout history for different applications and with different definitions. Examples include the Dutch metric ounce (100g), French ounce (30.59g), and the Spanish ounce (28.75g), among others. The current definition of the ounce, the international avoirdupois ounce was adopted in 1959.
Current use: The ounce is still a standard unit of mass in the US customary system of measurement. It is mostly used in the United States for measuring packaged food products, food portions, and postal items, among other things. The ounce is still used in some other countries around the world that have roots in British history and culture. Due to metrication, the United Kingdom (UK) no longer officially uses the ounce. It is however, still used in some settings in the UK, such as restaurants.
Stone
Definition: A stone (symbol: st) is an English and imperial unit of mass. It is defined as 14 pounds or 6.35029318 kilograms.
History/origin: The name "stone" is derived from the use of stones as weights since antiquity. Standardized stones were historically used for trade in England as well as some countries in northern Europe. In England, the stone had multiple definitions throughout history, based on the commodity and on local standards. In 1350, the stone was standardized to be used for wool at a weight of 14 pounds, and in 1835, the United Kingdom adopted this definition for use in the imperial system.
Current use: The stone as a unit of mass is used mostly in the United Kingdom for measuring body weight. Most other countries measure body weight in kilograms, and in some cases, in pounds.
