Convert horsepower (metric) hour to electron-volt
Please provide values below to convert horsepower (metric) hour [hp*h] to electron-volt [eV], or Convert electron-volt to horsepower (metric) hour.
How to Convert Horsepower (Metric) Hour to Electron-Volt
1 hp*h = 1.65262396405664e+25 eV
Example: convert 15 hp*h to eV:
15 hp*h = 15 × 1.65262396405664e+25 eV = 2.47893594608496e+26 eV

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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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.
Electron-Volt
An electron-volt (eV) is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing atomic and subatomic energies, especially in quantum physics and particle physics, replacing larger units like the joule for small-scale energies.
Current Use
The electron-volt is widely used in physics and chemistry to quantify energies at the atomic and subatomic levels, such as in spectroscopy, particle physics, and quantum mechanics, due to its convenience in expressing small energy values.
