Online Voltage Converter

Accurately convert Volt, milliVolt, kiloVolt, and megaVolt. Free tool for electricity.

Electrical voltage measures the potential difference that drives electrons in a circuit, measured in Volts (V). Many networks globally use 220V, while others use 110-127V. Microcontrollers operate at 3.3V or 5V. Transmission lines reach up to 750 kV. Automotive batteries use 12V; electric vehicles operate between 400V and 800V. Ohm's Law relates voltage, current, and resistance: V = R × I. This converter covers mV, V, kV, and MV.

Frequently Asked Questions
