How to Convert Electronvolts to Microjoules
To convert electronvolts to microjoules, multiply the energy by the following conversion ratio: 1.602177e-13 microjoules/electronvolt.
Since one electronvolt is equal to 1.602177e-13 microjoules, you can use this simple formula to convert:
The energy in microjoules is equal to the energy in electronvolts multiplied by 1.602177e-13.
For example, here's how to convert 5 electronvolts to microjoules using the formula above.
How Many Microjoules Are in an Electronvolt?
There are 1.602177e-13 microjoules in an electronvolt, which is why we use this value in the formula above.
Our electronvolt to microjoule calculator automatically converts your energy measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Electronvolts and microjoules 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 Microjoule?
A microjoule is a unit of energy equal to 1/1,000,000 of a joule (0.000001 J). One-millionth of a Joule. [2]
The microjoule is classified as a metric and SI-compatible unit of energy. Microjoules can be abbreviated as µJ; for example, 1 microjoule can be written as 1 µJ.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microjoule (µJ) a convenient decimal multiple of the joule (J).
In practice, microjoules (µJ) 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 microjoules (µJ), keep full floating-point precision (1 eV = 1.602177e-13 µJ; 1 µJ = 6.241509e+12 eV) during intermediate calculations and round only the final microjoule figure to match your instrument tolerance.
