MeV to eV Converter - Mega Electron Volt to Electron Volt

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

Direct answer

1 MeV = 1,000,000 eV

eV = MeV × 1,000,000

Converter

Input

MeV

Result

1,000,000eV

eV = MeV × 1,000,000

MeV = eV × 0.000001

Example: 10 MeV = 10 × 1,000,000 = 10,000,000 eV.

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

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

1 MeV = 1,000,000 eV.

10 MeV = 10,000,000 eV.

100 MeV = 100,000,000 eV.

Use eV = MeV × 1,000,000.

1 eV = 0.000001 MeV.

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