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.
Hectogram
A hectogram (hg) is a unit of mass equal to 100 grams.
History/Origin
The hectogram is part of the metric system, introduced in the 19th century as a decimal-based system for standardizing measurements, primarily used in scientific and everyday contexts.
Current Use
The hectogram is used in some countries for measuring food and other small quantities, especially in the context of nutrition labels and grocery shopping, but is less common than grams and kilograms.
