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.
Picogram
A picogram (pg) is a unit of mass equal to one trillionth (10^-12) of a gram.
History/Origin
The picogram was introduced as part of the metric system to measure extremely small masses, especially in scientific and laboratory contexts, as a subdivision of the gram in the SI unit system.
Current Use
Picograms are used in scientific fields such as biology, chemistry, and physics to measure very small quantities of substances, including DNA, proteins, and other microscopic materials.
