- 1 MeV = 1000 keV
- 1 × 1000 = 1000 keV
How to convert megaelectronvolts to kiloelectronvolts
1 MeV = 1,000 keV, so multiply by 1,000 to go from megaelectronvolts to kiloelectronvolts. Going the other way, 1 keV = 0.001 MeV.
keV = MeV × 1,000 MeV = keV × 0.001
Worked example:
1 MeV = 1000 keV 5 × 1000 = 5000 keV
