📐 How to Use

  1. Select the unit of the voltage you have in the From dropdown and the unit you want returned in the To dropdown.
  2. Enter the voltage in the value input; the converted result appears straight away in the panel beneath the dropdowns.
  3. Press the swap arrows to invert the pair, for instance turning volts to millivolts into millivolts to volts, then Copy the figure.
  4. Pick a tile in the Common Electric Potential Conversions grid for an instant pair, or open an All Electric Potential Conversions link for a page with a stepped table.

❓ Frequently Asked Questions

QHow many millivolts are in 1 volt?
1 V is 1000 mV, and the same volt is 1,000,000 µV. Instrumentation output is usually quoted in the smaller units, so a 2.5 mV thermocouple signal is 0.0025 V and a 50 µV offset is far smaller still.
QWhat is 1 kV in volts?
1 kV equals 1000 V, and 1 MV is 1,000,000 V. Distribution lines are described in kilovolts because the numbers stay short: an 11 kV feeder is 11,000 V and a 400 kV line is 400,000 V.
QWhy is a statvolt 299.792458 volts?
Because the electrostatic CGS unit is defined through the same constant that fixes the meter, so the statvolt carries the digits of the speed of light. The abvolt, from the electromagnetic CGS set, is far smaller at a hundred-millionth of a volt.
QCan this tell me the power or current in a circuit?
No. It converts a potential difference from one unit into another. Working out power needs a second measured quantity, since power is voltage multiplied by current, and current has its own converter here.

ℹ️ About Electric Potential Conversion

Electric potential difference is the energy carried per unit of charge, with one volt moving one joule per coulomb. It is always a difference, which is why a single point in a circuit has a voltage only relative to a chosen reference such as ground. The prefixed volts cover an enormous working span, from the microvolts of a thermocouple to the hundreds of kilovolts on a transmission line. Two entries come from elsewhere: the abvolt of the CGS electromagnetic system, and the statvolt, whose size of 299.792458 V is the speed of light in disguise.

Eight units are listed and the volt is the common reference for all of them. Values of ten and above are shown to four decimal places, smaller ones to six or eight, and anything under a ten-millionth switches to exponential form. Each keystroke is converted in the browser.
