Voltage Converter

Voltage is the electric potential difference that drives current through a circuit. The SI unit is the volt. Sensors and thermocouples output millivolts and microvolts, household outlets use volts, and transmission lines carry hundreds of kilovolts. CGS abvolts and statvolts still appear in older physics texts.

11 units supported Base unit volt (V)

1 V
1,000 mV

Multiply the number of volts by 1000 to get millivolts. How this is calculated

Copy link puts your number after the #, which browsers never send to a server — but the link itself carries it, so anyone you send it to sees the value. Save keeps the unit pair in this browser only; clear it any time from your saved list.
