How to Convert Voltage Units?

Voltage (electric potential difference) is measured in Volts, named after Alessandro Volta. Converting between voltage units uses standard metric prefixes: milli (1/1000), micro (1/1000000), kilo (1000), and mega (1000000). Our converter provides precise conversions for applications ranging from microelectronics to power transmission systems.

Units

Volt (V)

The SI unit of electric potential difference. One Volt is the potential difference that will drive one Ampere of current through a resistance of one Ohm. Common household voltages are 120V (North America) or 230V (Europe). USB devices operate at 5V.

Millivolt (mV)

One thousandth of a Volt (0.001 V). Used in sensors, thermocouples, and biomedical applications. ECG signals are typically measured in millivolts. Battery cells often show voltage differences in millivolts during testing.

Microvolt (µV)

One millionth of a Volt (0.000001 V). Essential in medical instrumentation for measuring brain waves (EEG), sensitive scientific instruments, and low-noise amplifier specifications. Human brain signals are in the microvolt range.

Kilovolt (kV)

One thousand Volts. Used in power distribution, X-ray machines, and industrial applications. Residential power lines typically carry 4-35 kV, while high-voltage transmission lines operate at 110-765 kV.

Megavolt (MV)

One million Volts. Found in ultra-high voltage power transmission, particle accelerators, and lightning research. Lightning strikes can produce voltages exceeding 100 MV. Some power transmission systems operate at 1 MV or higher.
