Convert kiloelectron-volt to kilowatt-second
Please provide values below to convert kiloelectron-volt [keV] to kilowatt-second [kW*s], or Convert kilowatt-second to kiloelectron-volt.
1 keV = 1.6022e-19 kW*s. To convert kiloelectron-volt to kilowatt-second, multiply the value by 1.6022e-19; to go the other way, divide by it (1 kW*s = 6.2415e+18 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 = 1.6022e-19 kW*s
- 1 kW*s = 6.2415e+18 keV
- 10 keV = 1.6022e-18 kW*s
- 100 keV = 1.6022e-17 kW*s
How to Convert Kiloelectron-Volt to Kilowatt-Second
1 keV = 1.602176634e-19 kW*s
Example: convert 15 keV to kW*s:
15 keV = 15 × 1.602176634e-19 kW*s = 2.403264951e-18 kW*s

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.
Kilowatt-Second
A kilowatt-second (kW·s) is a unit of energy equal to the energy transferred or converted when a power of one kilowatt is applied for one second.
History/Origin
The kilowatt-second has been used historically in physics and engineering to quantify energy, especially in contexts where power and time are relevant, but it is less common than other energy units like joules or kilowatt-hours.
Current Use
Today, the kilowatt-second is primarily used in specialized fields such as electrical engineering and energy calculations, often for convenience in measuring short-term energy transfer, but it is largely replaced by the joule in most applications.
