Attogram
An attogram (ag) is a unit of mass equal to 10^-18 grams, used to measure extremely small quantities.
History/Origin
The attogram was introduced as part of the metric system's expansion to include smaller units for scientific measurements, particularly in fields like nanotechnology and molecular biology, during the 20th century.
Current Use
Attograms are primarily used in scientific research to quantify very small masses, such as individual molecules or nanoparticles, and are part of the SI units for precise measurements in advanced scientific applications.
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.
