**Full name:** attovolt

**Plural form:** attovolts

**Symbol:** aV

**Category type:** voltage

**Scale factor:** 1.0E-18

The SI derived unit for voltage is the volt.

1 volt is equal to 1.0E+18 attovolt.

Valid units must be of the **voltage** type.

You can use this form to select from known units:

The SI prefix "atto" represents a factor of
10^{-18}, or in exponential notation, 1E-18.

So 1 attovolt = 10^{-18} 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.[3] Hence, it is the base SI representation m^{2} · kg · s^{-3} · A^{-1}, which can be equally represented as one joule of energy per coulomb of charge, J/C.
