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.
Quintal (Metric)
A quintal (metric) is a unit of mass equal to 100 kilograms.
History/Origin
The metric quintal originated in France in the 19th century as a standard unit of mass for trade and agriculture, replacing older local units. It is part of the metric system established during the French Revolution.
Current Use
The metric quintal is used primarily in agriculture and trade in some countries to measure large quantities of produce, though its use is less common today with the widespread adoption of the kilogram as the standard unit of mass.
