Dalton
The dalton (Da) is a unit of mass used to express atomic and molecular weights, equivalent to one atomic mass unit (amu).
History/Origin
The dalton was named after John Dalton, who developed early atomic theory in the early 19th century. It has been widely used in chemistry and biochemistry to measure atomic and molecular masses.
Current Use
The dalton is commonly used in scientific contexts to specify the mass of atoms, molecules, and subatomic particles, facilitating precise communication in chemistry, biochemistry, and molecular biology.
Petagram
A petagram (Pg) is a unit of mass equal to 10^15 grams or one quadrillion grams.
History/Origin
The petagram was introduced as part of the metric system's prefixes to represent extremely large masses, following the adoption of the International System of Units (SI). It is derived from the prefix 'peta-' which denotes 10^15.
Current Use
The petagram is primarily used in scientific contexts to quantify very large masses, such as in astronomy and geology, but is rarely used in everyday measurements.
