How to Convert Electronvolts to Nanojoules
To convert electronvolts to nanojoules, multiply the energy by the following conversion ratio: 1.602177e-10 nanojoules/electronvolt.
Since one electronvolt is equal to 1.602177e-10 nanojoules, you can use this simple formula to convert:
The energy in nanojoules is equal to the energy in electronvolts multiplied by 1.602177e-10.
For example, here's how to convert 5 electronvolts to nanojoules using the formula above.
How Many Nanojoules Are in an Electronvolt?
There are 1.602177e-10 nanojoules in an electronvolt, which is why we use this value in the formula above.
Our electronvolt to nanojoule calculator automatically converts your energy measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Electronvolts and nanojoules are both units used to measure energy. Keep reading to learn more about each unit.
What Is an Electronvolt?
An electronvolt is a unit of energy equal to 1/6,241,509,074,460,763,000 of a joule (1.602177e-19 J). Atomic energy unit equal to 1.602176634×10⁻¹⁹ Joules. [1]
The electronvolt is classified as an International System of Units (SI) unit of energy. Electronvolts can be abbreviated as eV; for example, 1 electronvolt can be written as 1 eV.
When working with electronvolts (eV) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, electronvolts (eV) are widely used across fine-tolerance laboratory, analytical, and micro-scale energy measurements within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a Nanojoule?
A nanojoule is a unit of energy equal to 1/1,000,000,000 of a joule (1e-9 J). One-billionth of a Joule. [2]
The nanojoule is classified as a metric and SI-compatible unit of energy. Nanojoules can be abbreviated as nJ; for example, 1 nanojoule can be written as 1 nJ.
In the metric system, "nano" is the standard SI prefix for billionths, or 10⁻⁹. This makes the nanojoule (nJ) a convenient decimal multiple of the joule (J).
In practice, nanojoules (nJ) are widely used across fine-tolerance laboratory, analytical, and micro-scale energy measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting energy between electronvolts (eV) and nanojoules (nJ), keep full floating-point precision (1 eV = 1.602177e-10 nJ; 1 nJ = 6,241,509,074.460763 eV) during intermediate calculations and round only the final nanojoule figure to match your instrument tolerance.
