dalton
- Definition: The dalton, also known as the unified atomic mass unit (u), is a standard unit of mass used to express atomic and molecular weights.
- Symbol: The symbol for dalton is “Da”.
- Usage: It is primarily used in the fields of chemistry and biochemistry to quantify the mass of atoms and molecules.
pennyweight
- Definition: The pennyweight is a unit of mass that is traditionally used in the precious metals market. It is equal to 1/20 of a troy ounce.
- Symbol: The symbol for pennyweight is “dwt”.
- Usage: It is commonly used to measure precious metals like gold and silver, especially in jewelry making and trading.
Origin of the dalton
- The dalton is named after the English chemist John Dalton, who is best known for his work in atomic theory. Dalton proposed that each element consists of atoms of a single, unique type and that the weight of these atoms can be measured relative to hydrogen, which is assigned a mass of one.
Origin of the pennyweight
- The term pennyweight has its roots in the historical practice of weighing coins. The pennyweight was originally defined as the weight of a silver penny in the 16th century, which eventually became standardized as a unit of measure for precious metals.
