Convert poundal foot to Rydberg constant
Please provide values below to convert poundal foot [pdl*ft] to Rydberg constant [Ry], or Convert Rydberg constant to poundal foot.
1 pdl*ft = 1.9331e+16 Ry. To convert poundal foot to Rydberg constant, multiply the value by 1.9331e+16; to go the other way, divide by it (1 Ry = 5.1729e-17 pdl*ft). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Poundal Foot
The poundal foot (pdl*ft) is a unit of energy representing the work done when a force of one poundal acts over a distance of one foot.
History/Origin
The poundal foot originated in the foot-poundal system of units, which was used primarily in the 19th and early 20th centuries in engineering and physics before the widespread adoption of the SI system.
Current Use
The poundal foot is rarely used today and has been largely replaced by the joule in scientific and engineering contexts. It may still appear in historical references or specialized fields dealing with imperial units.
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.
