Pound
The pound (lbs) is a unit of weight or mass commonly used in the United States and other countries, equivalent to 16 ounces or approximately 0.453592 kilograms.
History/Origin
The pound has origins in ancient Roman and Anglo-Saxon systems, evolving over centuries into its current form. It was historically based on various standards, including the Tower pound and the avoirdupois pound, with the latter becoming the standard in most countries.
Current Use
Today, the pound is primarily used in the United States for measuring body weight, food products, and other goods. It remains a standard unit in certain industries and is part of the imperial and US customary measurement systems.
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.
