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.
Calorie (It)
The calorie (cal) is a unit of energy traditionally used to quantify the amount of heat required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.
History/Origin
The calorie was originally defined in the 19th century as a unit of heat energy in thermodynamics. It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts. The 'small calorie' (cal) is distinct from the 'large calorie' (kcal), which is commonly used in food energy labeling.
Current Use
Today, the calorie is primarily used in nutrition to measure the energy content of foods and beverages, although the SI unit of energy, the joule, is increasingly preferred in scientific and technical fields.
