Voltage conversion family
Voltage unit conversions
Electric potential difference, commonly called voltage, uses the volt (V), the coherent SI derived unit equal to watt per ampere.
Five named units
Unit and factor reference
| Unit | Symbol | Factor to base | Relationship | Definition and variant |
|---|---|---|---|---|
| volt | V | 1 | defined | The volt is the coherent SI derived unit of electric potential difference: 1 V = 1 W/A. The base factor is exactly 1 by the family base-unit choice. |
| millivolt | mV | 0.001 | exact | A millivolt is the SI decimal submultiple formed by applying milli (10^-3) to volt: 1 mV = 0.001 V. The decimal-prefix relationship is exact. |
| microvolt | µV | 0.000001 | exact | A microvolt is the SI decimal submultiple formed by applying micro (10^-6) to volt: 1 µV = 0.000001 V. The decimal-prefix relationship is exact. |
| kilovolt | kV | 1000 | exact | A kilovolt is the SI decimal multiple formed by applying kilo (10^3) to volt: 1 kV = 1000 V. The decimal-prefix relationship is exact. |
| megavolt | MV | 1000000 | exact | A megavolt is the SI decimal multiple formed by applying mega (10^6) to volt: 1 MV = 1000000 V. The decimal-prefix relationship is exact. |

Evidence and review status
This family is machine-reviewed-pending-human. Automated checks verify structure, factor parity and source references; they do not constitute human or specialist approval.
Family assumptions and limits
- Signed values preserve reference polarity: a negative voltage means the measured polarity is opposite the chosen positive reference.
- This family performs unit scaling only; it does not distinguish DC, AC RMS, peak, peak-to-peak, line-to-line, line-to-neutral, or phasor values.
- Voltage drop, electromotive force, and electric potential difference can share the volt but require contextual interpretation outside this converter.
- A conversion does not add significant figures to the source measurement.
