Deuteron Mass
The deuteron mass (m_d) is the mass of a deuteron, which is the nucleus of deuterium consisting of one proton and one neutron, approximately 3.3436 × 10^-27 kilograms.
History/Origin
The deuteron mass has been determined through nuclear physics experiments involving mass spectrometry and nuclear reactions, with precise measurements becoming available in the 20th century as experimental techniques advanced.
Current Use
The deuteron mass is used in nuclear physics, astrophysics, and related fields to calculate nuclear reactions, binding energies, and in the calibration of mass spectrometers involving deuterium nuclei.
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.
