What this calculator does
Converts a measurement given in electronvolts into ergs using the defined conversion factor.
What your result means
The same quantity expressed in erg instead of eV. Nothing about the measurement itself changes.
Formula and working
erg = eV × 1.6022e-12
- 1
Start with your value
1,000 eV
- 2
Convert to joule
1,000 × 1.6022e-19 = 1.6022e-16 J
- 3
Convert into ergs
1.6022e-16 ÷ 1.0000e-7 = 1.6022e-9 erg
- 4
Result
1,000 eV = 1.6022e-9 erg
Frequently asked questions
Symbols and assumptions
- eV
- Input unit — electronvolt
- erg
- Output unit — erg
- J
- Base unit used internally for energy, work and heat
- • Both units measure energy, work and heat, so the physical quantity is unchanged by the conversion.
- • The relationship is exactly linear: 1 eV = 1.6022e-12 erg.
- • Values are converted through the SI base unit for this quantity rather than pair by pair.
Sources and review

- • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
- • Displayed figures are rounded for readability; the full stored precision of the erg value is used in every onward calculation.
