What is an erg used to measure?

An erg is a unit of energy in the CGS system commonly used for mechanical, thermal, or electromagnetic energies, such as in astrophysics and classical mechanics.

Where is the megaelectron-volt [MeV] unit commonly applied?

MeV quantifies energies at atomic and subatomic levels, including nuclear decays, particle accelerators, and photon energies like those in medical imaging.

How do I convert erg to MeV?

Multiply the energy value in erg by 624150.9074461 to get the equivalent energy in megaelectron-volt (MeV).
