Exact factor1 GeV = 1000000000 eV

eV → GeVGeV = eV × 1/1000000000

iLinear conversion using factor 1000000000. Prefer the exact factor over rounded multipliers when precision matters.

How to use

1

Choose GeV → eV or eV → GeV

Use the tabs to switch direction. Forward mode needs gigaelectronvolts; 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.
