Ounce
An ounce (oz) is a unit of weight or mass used primarily in the United States and other countries that use the imperial system. It is equal to 1/16 of a pound or approximately 28.35 grams.
History/Origin
The ounce has origins in ancient Roman and medieval systems of weight measurement. It was historically used in various forms across different cultures, with the modern avoirdupois ounce standardized in the 14th century in England to facilitate trade and commerce.
Current Use
Today, the ounce is commonly used to measure food ingredients, precious metals, and other small quantities of weight in the United States and other countries using the imperial system. It is also used in the context of jewelry, cooking, and postal services.
Atomic Mass Unit
The atomic mass unit (u) is a standard unit of mass used to express atomic and molecular weights, defined as one twelfth of the mass of a carbon-12 atom.
History/Origin
The atomic mass unit was introduced in the early 20th century to provide a convenient scale for atomic weights. It was originally based on the mass of hydrogen but was later standardized to be one twelfth of the mass of a carbon-12 atom, which was adopted as a reference in 1961 by the IUPAC.
Current Use
The atomic mass unit is widely used in chemistry and physics to express atomic and molecular masses, facilitating calculations in molecular chemistry, nuclear physics, and related fields.
