electronvolt to nanojoule
Convert electronvolt (eV) to nanojoule (nJ). Use an editable energy converter, conversion formula, and reference table.
1 eV = 1.60217663e-10 nJ
Conversion formula
One electronvolt equals 1.60217663e-10 nanojoule. Multiply your value in electronvolt by this factor to get nanojoule. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 electronvolt:5 × 1.60217663e-10 = 8.01088317e-10 nJ

About these measurements
Energy can be transferred through work, heating, or electrical processes.
The base reference used here is the joule. One electronvolt is 1.60217663e-19 base units; one nanojoule is 1e-9 base units.
Important distinctions
Calorie and BTU definitions vary. These pages label thermochemical calories and International Table BTUs explicitly.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert eV to nJ?
Multiply the quantity in eV by 1.60217663e-10. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the nanojoule to electronvolt converter.
