Microgram
A microgram (µg) is a unit of mass equal to one millionth of a gram (10^-6 grams).
History/Origin
The microgram was introduced as part of the metric system to measure very small quantities, particularly in science and medicine, and has been widely used since the 20th century.
Current Use
Micrograms are commonly used today in fields such as pharmacology, nutrition, and chemistry to measure small amounts of substances accurately.
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.
