Quarter (Uk)
A quarter (qr) is a traditional unit of weight used in the UK, typically equal to one-quarter of a hundredweight, or 28 pounds (approximately 12.7 kilograms).
History/Origin
The quarter has historical roots in British measurement systems, originating from the need to divide larger weights into manageable parts. It was commonly used in trade and agriculture before the adoption of the metric system.
Current Use
Today, the quarter is largely obsolete in official measurement but may still be used informally in certain industries such as agriculture and livestock to denote weight, especially in the UK.
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.
