Facts about Ounce
Basic facts: An ounce is a unit of mass in the US customary and imperial systems of measurement. Its symbol is [oz]. The avoirdupois ounce, which is the common ounce, is defined as precisely 28.349523125 grams and is equal to one-sixteenth of an avoirdupois pound.
History: The term ounce originates from the Roman uncia, which means a [twelfth part] and the use of a standardized copper bar which defined the Roman pound as well as the foot. The copper bar was divided into twelve identical parts, called unciae. This relationship between the Roman pound and foot ultimately contributed to the uncia being the basis of both the modern inch and the common ounce. Throughout history, the ounce has been used as a standard of mass for various applications and with different definitions. Examples include the French ounce (30.59g), Spanish ounce (28.75g), and the Dutch metric ounce (100g) among others. In 1959, the current definition of the ounce, the international avoirdupois ounce was adopted.
Use: In the US customary system of measurement, an ounce is still a standard unit of mass. It is mainly used in the United States for food portions, measuring packaged food products, and postal items, among other things. In some other countries around the world that have roots in British history and culture, the ounce is still used. The United Kingdom no longer officially uses the ounce due to metrication. It is, however, still used in some settings (restaurants) in the United Kingdom.
