Quarter (Us)
A quarter (US) is a unit of weight equal to one-fourth of a pound, commonly used in measuring precious metals and other small quantities.
History/Origin
The quarter originated from the traditional British weight system and was adopted in the United States as a subdivision of the pound. It has historically been used in commerce and trade for precise measurements.
Current Use
Today, the quarter is primarily used in the United States for measuring precious metals, jewelry, and small quantities of certain commodities. It is part of the customary units in the 'Weight and Mass' category within common converters.
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.
