The SI unit of a voltmeter is the **volt (V)**.
A voltmeter measures electric potential difference (voltage) between two points in a circuit. The volt, which is the unit of this measurement, is defined as the potential difference required to move one joule of energy per coulomb of charge.
In summary, the voltmeter measures voltage in **volts (V)**, which is the SI unit.
