eV to MeV Converter - Electron Volt to Mega Electron Volt

Electron Volt (eV) to Mega Electron Volt (MeV)

Direct answer

1 eV = 0.000001 MeV

MeV = eV × 0.000001

Converter

Input

Result

0.000001MeV

MeV = eV × 0.000001

eV = MeV × 1,000,000

Example: 10 eV = 10 × 0.000001 = 0.00001 MeV.

Express both eV and MeV in the same base unit J (joule), then cancel the shared base unit.

1
Rewrite eV in the base unit
$1 eV = 1.60217663 \times 1 0^{- 19} J$
2
Rewrite MeV in the base unit
$1 MeV = 1.60217663 \times 1 0^{- 13} J$
3
Forward conversion
$1 eV = \frac{1.60217663 \times 1 0 ^{- 19} J}{1.60217663 \times 1 0 ^{- 13} J} \times 1 MeV = \frac{1.60217663 \times 1 0 ^{- 19}}{1.60217663 \times 1 0 ^{- 13}} MeV = 0.000001 MeV$
4
Reverse conversion
$1 MeV = \frac{1.60217663 \times 1 0 ^{- 13} J}{1.60217663 \times 1 0 ^{- 19} J} \times 1 eV = \frac{1.60217663 \times 1 0 ^{- 13}}{1.60217663 \times 1 0 ^{- 19}} eV = 1, 000, 000 eV$

1 eV = 0.000001 MeV.

10 eV = 0.00001 MeV.

100 eV = 0.0001 MeV.

Use MeV = eV × 0.000001.

1 MeV = 1,000,000 eV.

Use the conversion factor and round the result to the precision required by your calculation.
