Convert Voltage Units
Enter a voltage value. Select the source and target units. Adjust the output options as needed.
Formula Used
Volts = Millivolts ÷ 1,000
Millivolts = Volts × 1,000
One millivolt equals one-thousandth of a volt. The calculator first converts every input into volts. It then converts volts into the selected target unit.
