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.
Centigram
A centigram (cg) is a unit of mass equal to one hundredth of a gram, primarily used for measuring small quantities.
History/Origin
The centigram was introduced as part of the metric system in the 19th century to facilitate precise measurements in science and commerce, especially in contexts requiring small mass units.
Current Use
Today, the centigram is mainly used in scientific, medical, and jewelry contexts where precise small measurements are necessary, although grams are more commonly used in everyday applications.
