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.
Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
