maratoolHow to convert volts, millivolts, and kilovolts
Type a potential — read µV, mV, V, kV, or MV instantly.
EEG signals are microvolts, logic levels are volts, and transmission lines are hundreds of kilovolts. The Electric Potential Converter spans that whole range with exact prefixes.
How it works
- Pick units — "Millivolt (mV)" to "Volt (V)", or any other pair.
- Type a value — the result updates as you type, with swap and copy.
- Copy — one click, with "Copied!" feedback.
Electric potential conversion factors
Every unit converts through the volt (the base unit). To convert A → B, multiply by A's factor and divide by B's:
| Unit | = this many volts |
|---|---|
| Megavolt (MV) | 1,000,000 |
| Kilovolt (kV) | 1,000 |
| Volt (V) | 1 |
| Millivolt (mV) | 0.001 |
| Microvolt (µV) | 1.0000 × 10^-6 |
| Abvolt (abV) | 1.0000 × 10^-8 |
| Statvolt (statV) | 299.792458 |
When you need it
Scale check: thermocouples output ~41 µV/°C, lithium cells sit at 3.7 V, EV fast chargers run 400–800 V, and long-distance HVDC lines reach ±800 kV — nine orders of magnitude, all one unit.
Sources & methodology
Conversion factors follow NIST Special Publication 811; exact-by-definition factors are marked in the tool itself. All math runs client-side in your browser — nothing is uploaded.
