ELECTRIC POTENTIAL WORKSPACE

Voltage Converter

Convert volts, millivolts, microvolts, kilovolts, and megavolts through exact decimal SI prefixes with the calculation visible.

Reviewed reference factorsValues stay in this browser tabNon-negative voltage magnitudes only; polarity, waveform, voltage drop, insulation, and safety are outside scope.

Conversion input

Convert a known voltage magnitude

Enter an electric potential difference and choose the prefix shown by the source. The result changes units without altering the measurement convention.

Find a unit5 / 5

Filter by unit name, symbol, or code. Your current selections remain available.

Known value0 / 80

Enter a non-negative voltage magnitude. Preserve DC polarity or the AC RMS, peak, or peak-to-peak convention separately.

Convert from

Choose the unit attached to the value you entered.

Convert to

Choose the unit required for your report, estimate, or comparison.

Displayed precision

Choose the maximum decimal places shown. This does not increase source accuracy.

Conversion runs locally after the active reference catalogue loads.

Conversion result

Your checked conversion appears here

Load the 11000 V example or enter voltage to compare every available SI-prefix equivalent.

What this tool delivers

Voltage prefixes converted without a circuit model

The workspace changes the numeric scale of a supplied potential difference; it does not calculate source, load, or conductor behavior.

What it converts

Converts one voltage magnitude among decimal SI volt multiples and submultiples.

What you provide

A non-negative voltage, its exact source prefix and measurement convention, a destination, and precision.

What you receive

A selected voltage, the volt conversion equation, all available equivalents, and a CSV table.

Calculation method

How volt prefixes scale potential difference

The source magnitude is multiplied by its volts-per-unit factor and divided by the destination factor. Decimal prefixes remain explicit, so a millivolt-to-kilovolt change can be audited directly.

Quick answers

Voltage Converter questions

Does converting voltage calculate voltage drop?

No. Conversion only changes the unit used to express an existing potential difference. Voltage drop requires a circuit model with current, conductor impedance, length, connections, temperature, frequency, and load behavior. Use the converted number as an input only after confirming that all quantities use compatible conventions.

Can AC RMS and peak voltage use the same conversion?

The SI prefix conversion is the same, but RMS and peak are not the same measured quantity. This page does not transform between waveform conventions. Keep RMS, peak, peak-to-peak, average, and DC labels attached to the number, and use a waveform-specific relationship only when its assumptions are valid.

Does a kilovolt result mean the equipment is suitable?

No. A converted magnitude says nothing about insulation class, transient overvoltage, creepage, clearance, frequency, grounding, environment, enclosure, or regulatory approval. Compare the correctly labelled value with current manufacturer data and governing standards, and always use qualified electrical review in service whenever hazardous energy may be present.
