An electron-volt, symbolized as eV, is a unit of energy equal to approximately 1.602×10^-19 joules. It represents the amount of kinetic energy gained or lost by a single electron when it is accelerated through an electric potential difference of one volt. In the field of physics, particularly in particle and atomic scales, the electron-volt is a convenient unit for measuring energy levels and particle interactions.
Definition of NanojouleA nanojoule, symbolized as nJ, is a unit of energy in the International System of Units (SI), equivalent to one billionth of a joule (10^-9 joules). This unit is commonly used in scientific and technological fields, especially in applications involving lasers and photonics, where energy transfers occur on a very small scale. Nanojoules are useful for describing energy levels in microscopic systems where minute amounts of energy are significant.

Example 1:
convert 5 eV to nJ:
5 eV = 5 × 0.1602 nJ = 0.801 nJ
Example 2:
convert 10 eV to nJ:
10 eV = 10 × 0.1602 nJ = 1.602 nJ
The concept of converting electron-volts to nanojoules stems from the need to relate quantum energy levels to macroscopic energy units. The conversion factor for electron-volts to joules is established using the charge of an electron. Over time, the conversion has become a standard practice in fields such as particle physics and semiconductor technology, making it easier to relate small-scale energy measurements to more familiar units.
