How to use Voltage Converter

Enter a value and pick its unit (Volts, millivolts, kilovolts, megavolts, microvolts), and the tool converts it to every other voltage unit live.

Frequently asked questions

How many millivolts in a volt?

1 volt (V) = 1,000 millivolts (mV) = 1,000,000 microvolts (µV).

What voltage is a household outlet?

Household mains voltage is typically 120V (North America) or 220–240V (most of Europe, Asia and Africa).

How many volts in a kilovolt?

1 kilovolt (kV) = 1,000 volts, commonly used for power transmission lines.
