Btu (Th)
The Btu (th), or British thermal unit (th), is a unit of energy used primarily in the United States to measure heat content, equivalent to the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit.
History/Origin
The Btu (th) originated from the British thermal unit, a traditional unit of heat in the British Imperial system, and has been used historically in heating, cooling, and energy industries to quantify energy content and heat transfer.
Current Use
Today, the Btu (th) is mainly used in the energy sector, particularly in heating and cooling systems, natural gas billing, and energy content measurement, especially within the United States.
Rydberg Constant
The Rydberg constant (Ry) is a physical constant that represents the highest wavenumber (inverse wavelength) of any photon in the hydrogen atom's emission spectrum, used to calculate spectral lines.
History/Origin
Named after the Swedish physicist Johannes Rydberg, the Rydberg constant was introduced in the late 19th century as part of Rydberg's formula to describe the spectral lines of hydrogen, significantly advancing atomic physics.
Current Use
The Rydberg constant is used in quantum physics and spectroscopy to determine energy levels of hydrogen and other hydrogen-like atoms, and in calculations involving atomic spectra and quantum mechanics.
