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.
Femtogram
A femtogram (fg) is a unit of mass equal to 10^-15 grams.
History/Origin
The femtogram was introduced as part of the metric system's extension to measure extremely small masses, particularly in scientific fields such as chemistry and biology, during the 20th century as measurement technology advanced.
Current Use
Femtograms are used in scientific research to measure tiny quantities of substances, such as in molecular biology, nanotechnology, and materials science, where precise measurement of very small masses is required.
