GeV and eV are units of energy used in particle physics and quantum mechanics to express the energy of particles and subatomic phenomena.
This is a unit of energy commonly used in atomic and subatomic physics. It is defined as the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt. The electronvolt is a very small unit of energy, suitable for describing the energies of individual particles and the interactions between them on an atomic and molecular scale.
This is a larger unit of energy used to express energies on a much larger scale, typically in the realm of particle accelerators and high-energy physics. One gigaelectronvolt is equal to one billion electronvolts (109 eV). It is used to describe the energies of particles that are accelerated to very high speeds, such as those found in particle colliders like the Large Hadron Collider (LHC).
1 GeV = 109 eV
E(eV) = E(GeV) × 109 = E(GeV) × 1000000000
Example – Convert 5 GeV to eV
Ans. E(eV) = 5GeV × 109 = 5×109 eV

1 GeV (Gigaelectronvolt) is equivalent to approximately 1.602 × 10^-10 joules.
To convert voltage to electronvolts (eV), you can multiply the voltage value in volts by the elementary charge (1.602 × 10^-19 C), which gives you the energy in electronvolts.
The mass-energy equivalence, described by Einstein's equation E=mc², shows that 1 kg is equivalent to about 8.9875 × 10^16 GeV.
1 GeV (Gigaelectronvolt) is a unit of energy equal to approximately 1.602 × 10^-10 joules. It's commonly used in particle physics to express energies of particles and interactions.
GeV stands for Gigaelectronvolt, which is a unit of energy used to describe the energy levels and masses of particles in the realm of particle physics and nuclear interactions.
The energy of an electron is often expressed in electronvolts (eV) or kiloelectronvolts (keV), rather than GeV, due to the electron's relatively lower energy. An electron's energy is typically on the order of keV.
The full form of GeV is Gigaelectronvolt, where Giga denotes a factor of 10^9, and electronvolt is a unit of energy.
In particle physics, mass and energy are closely related through Einstein's equation E=mc². To convert energy (GeV) to mass (usually in kilograms), you can rearrange the equation as m = E/c², where c is the speed of light in a vacuum (approximately 3 × 10^8 m/s). This conversion allows you to find the mass corresponding to a given energy in GeV.
