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.
Slug
A slug is a unit of mass primarily used in the imperial system, equal to approximately 32.174 pounds or 14.5939 kilograms.
History/Origin
The slug was introduced in the 19th century as a unit of mass in the imperial system, named after the animal due to its slow movement, and has been used mainly in engineering and physics contexts within the United States.
Current Use
Today, the slug is primarily used in scientific and engineering calculations in the United States, especially in contexts involving imperial units, but it is largely replaced by the kilogram in most applications worldwide.
