Current Use
Today, the quarter is largely obsolete in official measurement but may still be used informally in certain industries such as agriculture and livestock to denote weight, especially in the UK.
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.
