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.
Milligram
A milligram (mg) is a unit of mass equal to one thousandth of a gram.
History/Origin
The milligram has been used in scientific and medical contexts for precise measurement of small quantities, especially in pharmacology and chemistry, with its origins linked to the metric system established in the 18th century.
Current Use
Today, the milligram is widely used in pharmaceuticals, nutrition, and scientific research to measure small amounts of substances accurately.
