Kiloelectron-Volt
A kiloelectron-volt (keV) is a unit of energy equal to 1,000 electron-volts, commonly used in atomic and nuclear physics to measure small amounts of energy.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing energies at the atomic scale, with the prefix 'kilo' added later to denote 1,000 electron-volts, especially in high-energy physics and astrophysics.
Current Use
The keV is widely used today in fields such as X-ray spectroscopy, astrophysics, and particle physics to quantify energies of particles, photons, and nuclear processes.
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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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.
