UnitConElectric Potential
Electric potential, usually called voltage, measures electric potential energy per unit charge. It ranges from tiny sensor signals in millivolts to power-transmission lines in kilovolts and lightning in megavolts. This converter helps compare those scales quickly. It is useful for electronics, power engineering, and education.

Frequently asked questions
Voltage is electric potential difference between two points. It describes how much energy each unit of charge can gain or lose between those points.
Voltage is potential difference, while current is charge flow rate. A circuit needs both the correct voltage and a current path to operate.
Common household voltages vary by region, with many countries using values around 120 V or 230 V. Exact standards depend on the local electrical system.
