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.
Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI), defined as the mass of the International Prototype Kilogram, a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures.
History/Origin
The kilogram was originally defined in 1795 as the mass of one liter of water. It was later represented by a platinum standard in 1875, known as the International Prototype Kilogram, which served as the global standard until 2019.
Current Use
Today, the kilogram is defined by the Planck constant, fixed at exactly 6.62607015×10⁻³⁴ joule seconds, ensuring greater precision and stability in measurements worldwide. It is widely used in science, industry, and commerce for measuring mass.
