eV and GeV are units of energy commonly used in physics to measure the energy of particles and the interactions between them. They stand for electronvolt (eV) and gigaelectronvolt (GeV), respectively.
An electronvolt is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt. It is a convenient unit for expressing energies at the atomic and subatomic scale. The electronvolt is a very small unit of energy, suitable for measuring the energies of particles in particle physics and quantum mechanics.

A gigaelectronvolt is a billion electronvolts. It’s often used to describe the energy levels of particles in high-energy particle physics, such as in particle accelerators like the Large Hadron Collider (LHC) at CERN. Since particle collisions in these accelerators can result in very high energies, the GeV unit provides a more practical way to express these energies without using excessively small numbers.
1 GeV = 1,000,000,000 eV = 1.602176634 × 10-10 joules
1 GeV = 109 eV
E(GeV) = E(eV) / 109 = E(eV) / 1000000000
Example – Convert 5eV to GeV
Ans. E(GeV) = 5eV / 109 = 5×10-9GeV

Electronvolts (eV) and voltage are related in certain contexts, but they measure different quantities. Electronvolts are a unit of energy, while voltage is a measure of electric potential difference. To convert eV to voltage, you need additional information about the system, such as the charge of the particles involved and the distance they travel.
1 GeV (gigaelectronvolt) is equal to 1 billion electronvolts (1 x 10^9 eV). It represents a significant amount of energy on the atomic and subatomic scale.
The conversion between electronvolts (eV) and volts (V) depends on the charge of the particle. For an electron, the charge is approximately -1.602 x 10^-19 coulombs. So, 1 eV is equivalent to about 1.602 x 10^-19 volts.
1 eV (electronvolt) is the amount of kinetic energy gained or lost by an electron when it moves through an electric potential difference of 1 volt. It's a small unit of energy commonly used in atomic and particle physics.
No, eV (electronvolt) is not the same as voltage. Electronvolt is a unit of energy, while voltage is a measure of electric potential difference (electric potential energy per unit charge).
Electronvolt (eV) measures energy, specifically the energy of individual particles like electrons. Volt (V) measures electric potential difference or the force that moves electric charges. They are related but used to quantify different aspects of electric and particle behavior.
The value of 1 electronvolt (eV) is approximately 1.602 x 10^-19 joules. This is the energy gained or lost by an electron when it moves through an electric potential difference of 1 volt.
