Convert horsepower (metric) hour to Rydberg constant
Please provide values below to convert horsepower (metric) hour [hp*h] to Rydberg constant [Ry], or Convert Rydberg constant to horsepower (metric) hour.
How to Convert Horsepower (Metric) Hour to Rydberg Constant
1 hp*h = 1.21465524086919e+24 Ry
Example: convert 15 hp*h to Ry:
15 hp*h = 15 × 1.21465524086919e+24 Ry = 1.82198286130378e+25 Ry

Horsepower (Metric) Hour
A unit of energy representing the amount of work done by one horsepower over one hour, equivalent to 745.7 joules.
History/Origin
The horsepower hour was historically used to quantify energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.
Current Use
It is rarely used in modern practice, but may still appear in legacy systems or specific industrial applications to measure energy output or consumption related to horsepower-rated equipment.
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.
