Megaelectronvolts to Kiloelectronvolts Converter

1 megaelectronvolt (MeV) equals 1,000 kiloelectronvolts (keV).

Quick answer

  • 1 megaelectronvolt = 1,000 kiloelectronvolts
  • 1 kiloelectronvolt = 0.001 megaelectronvolts
  • Formula: keV = MeV × 1,000

1 megaelectronvolt = 1,000 kiloelectronvolts

How to convert megaelectronvolts to kiloelectronvolts

keV = MeV × 1,000

To convert megaelectronvolts to kiloelectronvolts, multiply the number of megaelectronvolts by 1,000.

Example: 4 MeV to keV

  1. Start with the value in megaelectronvolts: 4 MeV.
  2. Multiply by 1,000: 4 × 1,000 = 4,000.
  3. Result: 4 megaelectronvolts = 4,000 kiloelectronvolts.

Going the other way, 1 kiloelectronvolt = 0.001 megaelectronvolts, so to convert kiloelectronvolts back to megaelectronvolts you divide by the same number. See kiloelectronvolts to megaelectronvolts.
