To convert ergs to megaelectronvolts, multiply by 624150.9074.
The calculation uses 1 erg = 624150.9074 MeV. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
value in MeV = value in erg × 624150.9074
erg- Input unit: ergs
MeV- Output unit: megaelectronvolts
How to use this calculator
- Enter a value in erg.
- Multiply by the stored conversion factor.
- Read the result in MeV; divide by the same factor to convert back.
Worked examples

1 erg × 624150.9074 ≈ 624150.9074 MeV.
Reverse conversion
624150.9074 MeV ÷ 624150.9074 ≈ 1 erg. Rounding intermediate values can change the last displayed digit.
Frequently asked questions
What factor does this converter use?
It uses 624150.9074 MeV per erg.
Why can another converter show a slightly different answer?
Check the unit convention first (such as US versus Imperial or decimal versus binary), then compare rounding. Measurement uncertainty is separate from the unit conversion.
