Gigaelectronvolts to Kiloelectronvolts Converter

1 gigaelectronvolt (GeV) equals 1,000,000 kiloelectronvolts (keV).

Quick answer

  • 1 gigaelectronvolt = 1,000,000 kiloelectronvolts
  • 1 kiloelectronvolt = 0.000001 gigaelectronvolts
  • Formula: keV = GeV × 1,000,000

1 gigaelectronvolt = 1,000,000 kiloelectronvolts

How to convert gigaelectronvolts to kiloelectronvolts

keV = GeV × 1,000,000

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

Example: 4 GeV to keV

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

Going the other way, 1 kiloelectronvolt = 0.000001 gigaelectronvolts, so to convert kiloelectronvolts back to gigaelectronvolts you divide by the same number. See kiloelectronvolts to gigaelectronvolts.
