Convert kiloelectron-volt to watt-hour
Please provide values below to convert kiloelectron-volt [keV] to watt-hour [W*h], or Convert watt-hour to kiloelectron-volt.
1 keV = 4.4505e-20 W*h. To convert kiloelectron-volt to watt-hour, multiply the value by 4.4505e-20; to go the other way, divide by it (1 W*h = 2.2469e+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 = 4.4505e-20 W*h
- 1 W*h = 2.2469e+19 keV
- 10 keV = 4.4505e-19 W*h
- 100 keV = 4.4505e-18 W*h
How to Convert Kiloelectron-Volt to Watt-Hour
1 keV = 4.45049065e-20 W*h
Example: convert 15 keV to W*h:
15 keV = 15 × 4.45049065e-20 W*h = 6.675735975e-19 W*h

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-Hour
A watt-hour (W·h) is a unit of energy equal to the amount of energy transferred or used when one watt of power is sustained for one hour.
History/Origin
The watt-hour was established as a practical unit of energy measurement with the adoption of the International System of Units (SI) and has been used in electrical and energy industries to quantify energy consumption and storage since the 20th century.
Current Use
Watt-hours are commonly used to measure electrical energy consumption in household appliances, batteries, and energy storage systems, providing a convenient unit for billing, capacity ratings, and energy management.
