Facts about Pennyweight
Basic facts: A pennyweight [symbol: dwt] is a unit of mass equivalent to precisely 1.55517384 grams, about 0.054857 avoirdupois ounce, 1/240 of a troy pound, 1/20 of a troy ounce, and 24 grains. Its abbreviation is dwt, d standing for denarius which was an ancient Roman coin, and later used as the symbol of an old British penny.
History: The pound unit in use in England was the Tower pound, equivalent to 7,680 Tower grains [otherwise known as wheat grains]. The medieval English pennyweight was equal to 32 Tower grains. In 1527, Troy weights replaced Tower weights. The Troy weights were determined in such a way that the old Tower pound came out to precisely 5,400 Troy grains, the Tower pennyweight 22+1/2 Troy grains [and thus about 1.46 grams]. The English pennyweight was the Troy pennyweight of 24 Troy grains after 1527.
Use: Jewelers use the pennyweight in calculating the amount and cost of precious metals used in fabricating or casting jewelry, therefore, the pennyweight is the common weight used in the valuation and measurement of precious metals. Dentists and dental labs still use the pennyweight as the measure of precious metals in dental crowns and inlays.
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.
