Convert kiloelectron-volt to watt-second
Please provide values below to convert kiloelectron-volt [keV] to watt-second [W*s], or Convert watt-second to kiloelectron-volt.
1 keV = 1.6022e-16 W*s. To convert kiloelectron-volt to watt-second, multiply the value by 1.6022e-16; to go the other way, divide by it (1 W*s = 6.2415e+15 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-16 W*s
- 1 W*s = 6.2415e+15 keV
- 10 keV = 1.6022e-15 W*s
- 100 keV = 1.6022e-14 W*s
How to Convert Kiloelectron-Volt to Watt-Second
1 keV = 1.602176634e-16 W*s
Example: convert 15 keV to W*s:
15 keV = 15 × 1.602176634e-16 W*s = 2.403264951e-15 W*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.
Watt-Second
A watt-second (W·s) is a unit of energy equivalent to one joule, representing the amount of energy transferred or converted when one watt of power is applied for one second.
History/Origin
The watt-second originated from the SI system of units, where the watt (W) is the SI derived unit of power, and the second (s) is the SI base unit of time. It has been used historically in physics and engineering to quantify energy, especially in contexts where energy transfer occurs over short durations.
Current Use
The watt-second is primarily used in scientific and engineering contexts to measure small amounts of energy, such as in electrical and mechanical systems. It is often replaced by the joule in modern applications but remains a recognized unit within the energy converter category.
Frequently Asked Questions
