Btu (It)

The Btu (IT) is a unit of energy used to measure the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit, based on the International Table (IT) standards.

History/Origin

The Btu (IT) originated from the British thermal unit, adapted for international standards to provide a consistent measurement of heat energy, particularly in engineering and thermodynamics contexts.

Current Use

The Btu (IT) is primarily used in the energy industry, including heating, cooling, and power generation, to quantify energy content and efficiency in systems adhering to international standards.

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.
