Convert kiloelectron-volt to kilocalorie (th)
Please provide values below to convert kiloelectron-volt [keV] to kilocalorie (th) [kcal (th)], or Convert kilocalorie (th) to kiloelectron-volt.
1 keV = 3.8293e-20 kcal (th). To convert kiloelectron-volt to kilocalorie (th), multiply the value by 3.8293e-20; to go the other way, divide by it (1 kcal (th) = 2.6114e+19 keV). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 keV = 3.8293e-20 kcal (th)
- 1 kcal (th) = 2.6114e+19 keV
- 10 keV = 3.8293e-19 kcal (th)
- 100 keV = 3.8293e-18 kcal (th)

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.
Kilocalorie (Th)
A kilocalorie (kcal) is a unit of energy equal to 1,000 calories, commonly used to measure the energy content of food and beverages.
History/Origin
The kilocalorie originated in the 19th century as a unit to quantify heat energy, especially in nutrition and thermodynamics. It was widely adopted in the early 20th century for dietary energy measurement.
Current Use
Today, the kilocalorie is primarily used in nutrition to express the energy content of food and drinks, although it is often simply called a 'calorie' in everyday language.
