Voltage Converter
Loading tool...
Voltage, scientifically known as electrical potential difference, is the invisible pressure that forces electric charge (current) to flow through a circuit. Whether you're dealing with a tiny 3-Volt watch battery, a standard 120-Volt wall outlet, or high-tension power lines carrying hundreds of Kilovolts, understanding and converting these measurements is critical to electrical safety and engineering.
Our Voltage Converter helps electricians, physics students, and DIY electronics hobbyists translate electrical potential between standard international units effortlessly. A simple miscalculation in decimal places when converting Millivolts to Volts can fry delicate circuit boards like a Raspberry Pi or Arduino.
By using this free calculator, you can instantly translate any value across the electrical spectrum. Just enter your starting value, pick the units, and receive an instant, mathematically exact answer formatted specifically for easy reading.

Common Voltage Scales
What is a Volt (V)?
A Volt is the standard SI unit of electrical potential. Specifically, one volt is the potential difference required to move one ampere of current against one ohm of resistance.
Milli, Micro, and Kilo
A millivolt (mV) is a thousandth of a volt (0.001 V). A microvolt (µV) is a millionth of a volt (0.000001 V). A kilovolt (kV) is a thousand volts (1,000 V).
Frequently Asked Questions
Is Voltage the same as Wattage?
No. Voltage is the 'pressure' pushing the electricity. Amperage is the 'flow rate' of the electricity. Wattage is the total power produced by multiplying Voltage by Amperage (Watts = Volts × Amps).
What is a Statvolt?
A statvolt is the unit of voltage in the cgs-esu system (centimeter-gram-second electrostatic system). One statvolt is roughly equal to 299.79 volts. It is mostly used in theoretical physics.
Are these conversions completely accurate?
Yes. Since the primary units (mV, V, kV, MV) are standard decadal multiples of the SI Volt, the mathematical conversions are completely exact without subjective rounding.
