An electron-volt (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 by an electric potential difference of one volt across a vacuum. Initially used in atomic and particle physics, the electron-volt is now a standard measurement for expressing tiny amounts of energy.
Definition of MillijouleA millijoule (mJ) is a unit of energy in the International System of Units (SI) that is equal to one-thousandth of a joule, the SI unit of energy. One millijoule is equivalent to the energy transferred or work done when a force of one newton acts through a distance of one millimeter. This small energy unit is commonly used in various scientific and engineering applications.

1 mJ = 6.242 x 10^18 eV
Example 1:
Convert 5 eV to mJ:
5 eV = 5 × 1.602 x 10^-19 mJ = 8.01 x 10^-19 mJ
Example 2:
Convert 100 eV to mJ:
100 eV = 100 × 1.602 x 10^-19 mJ = 1.602 x 10^-17 mJ
The concept of the electron-volt emerged with the development of particle physics in the 20th century. It became a crucial unit for measuring tiny energy levels in quantum physics and in the field of high-energy particle physics. The conversion to millijoules is fundamental for bridging the gap between atomic energy scales and macroscopic energy measurements.

What is an electron-volt?
An electron-volt is a unit of energy corresponding to the energy gained by an electron when it moves through an electric potential difference of one volt.
How do you convert eV to mJ?
Use the conversion factor 1 eV = 1.602 x 10^-19 mJ and multiply the number of electron-volts by this factor to obtain the energy in millijoules.
Can this converter be used for large-scale energy conversions?
Yes, while eV is used for atomic-level energy, the converter can handle a wide range of values, making it suitable for larger conversions as well.
