Megaelectron-volts
A megaelectron-volt (MeV) is a unit of energy used in particle and nuclear physics. It is derived from the electron-volt (eV) - the amount of kinetic energy gained or lost by an electron when it moves through one volt.
Therm (US)
The Therm (US) is a unit of heat energy commonly used in the United States, particularly in the context of natural gas consumption. It is the amount of energy equivalent to burning 100 cubic feet of natural gas and is equivalent to about 105,480,400 joules.
