Stone (Us)
A stone (st) is a unit of weight primarily used in the United States, equal to 14 pounds or approximately 6.35 kilograms.
History/Origin
The stone has origins in medieval England, where it was used as a convenient weight measure for trade and commerce. Its value varied regionally before standardization, and it has been used historically for measuring human body weight and other goods.
Current Use
Today, the stone is mainly used in the UK and Ireland for body weight measurement, while in the United States, it is rarely used and often replaced by pounds or kilograms in most contexts.
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.
