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.
Fact about Pound
Basic facts: A pound is a unit of mass used in the United States customary and imperial systems of measurement. Its symbol is [lb.]. The common pound used today is the international avoirdupois pound. It is defined as precisely 0.45359237 kilograms. One avoirdupois pound is equal to 16 (sixteen) avoirdupois ounces.
History: Prior to the international avoirdupois pound that is widely used today, numerous different definitions of the pound were used throughout history. The pound descended from the Roman libra. The avoirdupois system was commonly used in the 13th century. In 1959, it was updated to its current form. This system was based on a physical standardized pound that used a prototype weight. This prototype weight could be divided into a number that had three even divisors [8, 4, 2] i.e., 16 ounces.
Use: In the United States, the pound as a unit of weight is widely used, often for measuring body weight. Many versions of the pound existed in the past in the UK, and although the United Kingdom largely uses the International System of Units, pounds are still used within specific contexts, such as labeling of packaged foods [by law the metric values must also be displayed]. The United Kingdom also often uses both pounds and stones when defining body weight, where a stone is comprised of 14 (fourteen) pounds.
