MeV → eVeV = MeV × 1000000

Exact factor1 MeV = 1000000 eV

eV → MeVMeV = eV × 1/1000000

iLinear conversion using factor 1000000. Prefer the exact factor over rounded multipliers when precision matters.

How to use

1

Choose MeV → eV or eV → MeV

Use the tabs to switch direction. Forward mode needs megaelectronvolts; reverse uses the opposite unit.

2

Enter the value

Type a non-negative value in the active unit field.

3

Convert and read the result

Use Convert or let the result update automatically.
