What is the Relation Between Electron Volt and Joule?

eV is the short form of Electron volt. It is a unit of energy. Particularly, this symbol is used in high-energy physics. An electronvolt is applied with an amount of energy. 1 eV is the amount of energy that helps an electron to gain energy by 1 volt.

eV has many forms, such as KeV, MeV, GeV, or TeV. They are the momentum units, and due to this energy, acceleration of the particle is possible.  

Also, Joule is the energy of work. It is a derived form of energy.  In this article, you will learn how to convert electron Volt into Joule.


eV to Joule Conversion 

Have you ever wondered about the Relation between joule and eV? Both Joule and eV are the units of energy. However, they are found in two different systems.

(Image to be added soon)

Scientists have predicted their relation in a mathematical form. Do you know, 1ev is equal to how many joules? 

1 eV to J can be written as:

1eV = 1.602×10-19 J

In the above expression, eV = Electron volt and J = Joule


How Do You Explain the Unit Joule?

A Unit Joule is the amount of work done or transfers of energy on an object with a force of 1 newton that acts on the object in the identical direction of its motion along 1 meter of distance.

The formula for 1 J = 6.2415×1018 eV

The conversion of eV to Joule is very significant. The values can be used to solve multiple problems in Physics. The table given below will show the conversion values of eV to Joule:

Electron-Volt to Joule conversion is also important for solving different types of problems in physics. The values given in the table are very useful for easier calculation.

You need to understand the concept and memorize the conversion values for better results. Both are commonly used as units of energy. The implementation of eV is everywhere, such as the atomic state, solid-state, nuclear physics, and particle physics

The value of 1eV is validated again under the redefinition of SI base units in 2019. Also, eV is used with different metric prefixes, such as mega-, kilo-, giga-, tera-, peta-, and exa-.

Also, the SI unit for energy is Joule. Both are different but can be related to each other. Volt and Electron volt are two identical units. eV is symbolized for energy whereas volt is the resultant SI unit from electric potential.

With the help of eV, physicists can also determine different values such as mass, momentum, time, distance, and temperature of an object. They do some mathematical calculations to achieve all these parameters.


FAQ (Frequently Asked Questions)

1. Do you know the conversion value of 1 eV to 1 Kilogram and vice versa?

The answer for 1eV to 1 kilogram is 1.782662E-36. Scientists have assumed certain conversion procedures to obtain the result. You know the SI unit of mass, i.e. Kg. 

So, 1 kilogram = 5.6095883571872E+35 Electron volt (excluding the errors).

2. What do you mean by MeV/c2?

MeV/c2 is a symbol. It says Million Electron volt per square of charge. You can call the given relationship a unit of mass. The energy of a particle can be calculated and displayed with the units of MeV. When the mass is considered with energy, the unit will become MeV/c2.

3. How do you relate between eV and Joules?

We know that Joule is a unit that comes from the energy (derived form). It is listed in the International System of Units. An electron volt is a pure energy coming out of electricity. eV is also coming under the SI unit list. Both the parameters are proportional to each other. Change in the value of J or eV will also change the other.

4. What is the value obtained after the conversion of 1 MeV into g-f-cm?

1 MeV is equal to 0.0000000016-gram force centimeters (g f cm)
