About Voltage Units
Voltage, also known as electric pressure or electric potential difference, is the difference in electric potential between two points. It is a fundamental parameter in electricity and electronics.
Volt (V)
The Volt is the derived unit for electric potential and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta. Standard household outlets typically provide 110V or 220V.
Millivolt (mV) & Kilovolt (kV)
A millivolt (mV) is one-thousandth of a volt, often used to measure tiny signals in electronics, sensors, and bioelectricity (like ECGs). A kilovolt (kV) is equal to one thousand volts, primarily used in high-voltage power transmission lines and heavy industrial equipment.
