Neutron Mass
The neutron mass (m_n) is the mass of a neutron, a subatomic particle found in the nucleus of an atom, approximately 1.675 × 10⁻²⁷ kilograms.
History/Origin
The neutron was discovered in 1932 by James Chadwick, leading to the understanding of its mass relative to protons and electrons. The neutron mass has been refined through experimental measurements in nuclear physics.
Current Use
The neutron mass is used in nuclear physics calculations, atomic mass units, and in the 'Weight and Mass' converter for scientific and educational purposes, as part of the 'Common Converters' category.
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and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
