Instantly convert between volts, millivolts, kilovolts, and microvolts with our powerful voltage conversion tool
Convert between different voltage units quickly and accurately
The standard unit of electric potential. One volt is defined as the difference in electric potential between two points that will impart one joule of energy per coulomb of charge.
One millivolt is equal to one-thousandth of a volt (1 mV = 0.001 V). Commonly used in electronics for measuring small voltage differences.
One kilovolt is equal to one thousand volts (1 kV = 1,000 V). Used in high-voltage applications like power transmission lines and industrial equipment.
One microvolt is equal to one-millionth of a volt (1 µV = 0.000001 V). Used for measuring very small voltages, such as in biological signals or sensitive sensors.
5 V = 5,000 mV
0.01 kV = 10 V
2,000,000 µV = 2 V
1.5 kV = 1,500,000 mV

Voltage spans an enormous range — microvolts in a sensor signal, volts in household circuits, kilovolts on a transmission line — and the units differ by factors of a thousand. This converter switches between volts, millivolts, kilovolts and microvolts in real time as you type. Each unit is explained on the page with its typical use, from small voltage differences in electronics to high-voltage industrial equipment and sensitive biological signals, so the tool teaches the scale while it converts. Worked examples (5 V = 5,000 mV; 0.01 kV = 10 V) make the relationships concrete.
It suits electronics hobbyists matching components, electricians and engineers checking specifications, and students learning electric potential. Free and mobile-friendly, with no sign-up and no tracking.
Volts (V), millivolts (mV), kilovolts (kV) and microvolts (µV).
1,000 mV. Likewise 1 kV = 1,000 V and 1 V = 1,000,000 µV — the converter handles every step of the scale.
For very small voltages, such as biological signals and sensitive sensor readings.
