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.
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.
