keV → eVeV = keV × 1000
Exact factor1 keV = 1000 eV
eV → keVkeV = eV ÷ 1000
iLinear conversion using factor 1000. Prefer the exact factor over rounded multipliers when precision matters.

How to use

1

Choose keV → eV or eV → keV

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