Convert kiloelectron-volt to megaelectron-volt
Please provide values below to convert kiloelectron-volt [keV] to megaelectron-volt [MeV], or Convert megaelectron-volt to kiloelectron-volt.
1 keV = 0.001 MeV. To convert kiloelectron-volt to megaelectron-volt, multiply the value by 0.001; to go the other way, divide by it (1 MeV = 1000 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 = 0.001 MeV
- 1 MeV = 1000 keV
- 10 keV = 0.01 MeV
- 100 keV = 0.1 MeV
How to Convert Kiloelectron-Volt to Megaelectron-Volt
1 keV = 0.001 MeV
Example: convert 15 keV to MeV:
15 keV = 15 × 0.001 MeV = 0.015 MeV

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.
Megaelectron-Volt
A megaelectron-volt (MeV) is a unit of energy equal to one million electron-volts, commonly used in nuclear and particle physics to express the energy of particles.
History/Origin
The megaelectron-volt was introduced as a convenient unit for expressing high-energy particles in physics, particularly after the development of particle accelerators in the mid-20th century, replacing the electron-volt for larger energy scales.
Current Use
Today, the MeV is widely used in nuclear physics, particle physics, and astrophysics to quantify the energy of subatomic particles, nuclear reactions, and cosmic phenomena.
Frequently Asked Questions
What is 1 kiloelectron-volt in megaelectron-volt?
1 kiloelectron-volt (keV) = 0.001 megaelectron-volt (MeV).
How do you convert kiloelectron-volt to megaelectron-volt?
Multiply the kiloelectron-volt value by 0.001. For example, 25 keV × 0.001 = 0.025 MeV.
What is 10 kiloelectron-volt in megaelectron-volt?
10 keV = 0.01 MeV.
Which unit is larger, the kiloelectron-volt or the megaelectron-volt?
The megaelectron-volt is the larger unit: 1 keV equals only 0.001 MeV.
