Convert calorie (th) to kiloelectron-volt
Please provide values below to convert calorie (th) [cal (th)] to kiloelectron-volt [keV], or Convert kiloelectron-volt to calorie (th).
1 cal (th) = 2.6114e+16 keV. To convert calorie (th) to kiloelectron-volt, multiply the value by 2.6114e+16; to go the other way, divide by it (1 keV = 3.8293e-17 cal (th)). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Calorie (Th)
The calorie (th) is a unit of energy used to quantify the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie (th) was historically used in the context of thermochemistry and nutrition, originating from the calorie concept in the 19th century. It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.
Current Use
Today, the calorie (th) is primarily used in nutrition labeling and food energy measurements, especially in regions where the thermochemical calorie is still recognized, although the joule is the SI standard.
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.
