Convert Rydberg constant to kilowatt-second

Please provide values below to convert Rydberg constant [Ry] to kilowatt-second [kW*s], or Convert kilowatt-second to Rydberg constant.

1 Ry = 2.1799e-21 kW*s. To convert Rydberg constant to kilowatt-second, multiply the value by 2.1799e-21; to go the other way, divide by it (1 kW*s = 4.5874e+20 Ry). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 Ry = 2.1799e-21 kW*s
  • 1 kW*s = 4.5874e+20 Ry
  • 10 Ry = 2.1799e-20 kW*s
  • 100 Ry = 2.1799e-19 kW*s

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.


Kilowatt-Second

A kilowatt-second (kW·s) is a unit of energy equal to the energy transferred or converted when a power of one kilowatt is applied for one second.

History/Origin

The kilowatt-second has been used historically in physics and engineering to quantify energy, especially in contexts where power and time are relevant, but it is less common than other energy units like joules or kilowatt-hours.

Current Use

Today, the kilowatt-second is primarily used in specialized fields such as electrical engineering and energy calculations, often for convenience in measuring short-term energy transfer, but it is largely replaced by the joule in most applications.
