Kiloelectronvolt (keV) to Megaelectronvolt (MeV) Conversion

Convert Kiloelectronvolt to Megaelectronvolt using the exact conversion factor. This page provides the formula, worked examples, and real-world use cases for practical understanding.

Conversion Formula

Megaelectronvolt = Kiloelectronvolt × 0.001

To convert Kiloelectronvolt (keV) to Megaelectronvolt (MeV), multiply the value by 0.001. This factor is obtained by comparing their exact meter definitions.

Worked Example

Convert 1 keV to MeV.

  • Step 1: Write the formula: MeV = keV × 0.001
  • Step 2: Substitute: 1 × 0.001
  • Step 3: Result: 0.001 MeV
So, 1 keV = 0.001 MeV.
