# ››Definition: Megavolt

The SI prefix "mega" represents a factor of 106, or in exponential notation, 1E6.

So 1 megavolt = 106 volts.

The definition of a volt is as follows:

The volt (symbol: V) is the SI derived unit of electric potential difference or electromotive force, commonly known as voltage. It is named in honor of the Lombard physicist Alessandro Volta (17451827), who invented the voltaic pile, the first chemical battery.

The volt is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power. Hence, it is the base SI representation m2 · kg · s-3 · A-1, which can be equally represented as one joule of energy per coulomb of charge, J/C.
