No need, just for convenience. Eg the mass of an electron is 9.11*10^-31 kg = 8.19*10^-14 J/c^2 = 512000 eV/c^2.
Which is the easier number to work with? The mass in kg or J/c^2 which is so tiny you can't really grasp it (and it makes maths trickier, you've got to remember to keep all those powers of 10) or the mass in eV/c^2.

In physics what is an electron volt?
In physics an electron volt is a very small unit of energy. An electron volt is the amount of energy gained by the charge of an electron once it has moved across an electric potential difference of one volt.
What is the electron-volt and how is it used as an alternate unit for measuring energy?
An electron-volt (eV) is a unit of energy used in physics. It is the amount of energy gained by an electron when it moves through an electric potential difference of one volt. Scientists use electron-volts as an alternate unit for measuring energy in subatomic particle interactions and in the field of particle physics.
What is the relation between 1 electron volt and 1 joule?
1 electron volt (eV) is equal to the amount of energy gained by an electron when it is accelerated through a potential difference of 1 volt. This energy amount is approximately equal to 1.6 x 10^-19 joules.
How would a proton-volt compare with electron volt if the mass of proton is 1840 time of electron?
A proton-volt (PV) would be 1840 times greater than an electron-volt (eV) since the mass of a proton is 1840 times greater than the mass of an electron. This means that one proton-volt is equivalent to 1840 electron-volts.
How much energy is stored in a one volt battery?
That can vary a lot, depending on the size of the battery. The "volt" is not an indication of energy stored. It simply means that (on average), each electron is pushed at a certain energy. To get the total energy, you would also need to know how much current it can provide, and for how long. The total energy can be calculated as the product of the voltage, the current, and how long this current flows (assuming a constant current; otherwise you would have to integrate).
Define electron volt?
An electron volt (eV) is a unit of energy equal to the energy gained by an electron as it moves through a potential difference of one volt. It is commonly used in atomic and subatomic physics to describe the energy of particles at the atomic and molecular scale.
In physics what is an electron volt?

What is the energy gap of a semiconductor?
It is in a range of 1eV. (eV=electron volt)
How is the electron volt related to the si unit of energy?
The SI unit of energy is the joule. The electron-volt, a non-standard (non-SI) unit, is equal to about 1.6 x 10-19 joule.
Will 2.0 250 volt replace a 1.6 125 volt?
You need to define what you mean by 2.0 and 1.6.
What is 7 trillion electron volts in mains voltage?
They're different things. An "electron volt" is not the same as a "volt". An "electron volt" is an amount of energy. It's the work you have to do in order to lift one electron to a place that's 1 volt more negative, and also the amount of energy that one electron loses when it falls to a place that's 1 volt more positive. "1 joule" of energy is the amount of energy you pay for if you use 1 watt for 1 second, and that's about 6,250,000,000,000,000,000 electron volts of energy. If you use 1,000 watts for 1 hour, you pay for 1 kilowatt-hour of energy. That's about 22,500,000,000,000,000,000,000,000 electron volts of energy, or 3.6 million joules. It costs around 15¢ to 25¢ in most places. The "7 trillion electron volts" in the question is something like the amount of energy that you'd have to pay for if you used 1 watt for 0.00000112 second. It's not much.
Can electronvolt converted to millivolt?
No; electron-volt is a measure of energy, not of voltage (or potential).
How many volts is 110keV?
There is no relationship between eV and V. An electron/volt is the energy acquired by an electron as it moves through an electric field of one volt. So 110 KeV is the energy acquired by an electron as it moves through an electric field of 110,000 volts.
What is the fundamental quantity of electricity indicating the ability to do work of forcing electrons to move?
The Electron Volt. Its the energy required to move one electron through a Potential Difference of one Volt. Commonly used to decribe size of particle accelerators 1 GeV , one Giga electron Volt , 1 X1012 electron Volts.
