Volt quick reference
| Volt | Millivolt | Microvolt | Kilovolt |
|---|---|---|---|
| 1 V | = 1000 mV | = 1000000 µV | = 0.001 kV |
| 10 V | = 10000 mV | = 10000000 µV | = 0.01 kV |
| 100 V | = 100000 mV | = 100000000 µV | = 0.1 kV |
| 1000 V | = 1000000 mV | = 1000000000 µV | = 1 kV |
Among the 7 electric potential (voltage) units on this page, the smallest is the abvolt (abV) and the largest is the megavolt (MV).

About electric potential (voltage) units
Electric potential difference, usually called voltage, is the energy per unit charge between two points. Its SI unit is the volt (V): one joule per coulomb, or one watt per ampere.
Household mains are around 120 V or 230 V depending on the country, and power lines run at many kilovolts. Sensors and thermocouples output millivolts, and brain signals (EEG) are measured in microvolts.
Frequently asked questions
- How many volts are in a kilovolt?
- Exactly 1000 volts.
- Can I convert volts to watts?
- Not directly. Power also depends on current: W = V × A. For example, 12 V at 2 A is 24 W.
- How many millivolts are in one volt?
- One volt = 1000 mV (millivolts).
- How many microvolts are in one volt?
- One volt = 1000000 µV (microvolts).
- How many kilovolts are in one volt?
- One volt = 0.001 kV (kilovolts).
